RESUMO

OBJECTIVE: to review the contribution of the Cincinnati Program Project grant (PPG) to the understanding and treatment of neonatal hypocalcemia (NHC) in infants of mothers with diabetes. STUDY DESIGN: retrospective review of the PPG publications related to mineral metabolism in type 1 diabetic pregnant women Results: the PPG investigators first described the epidemiology and the additional risk factors for NHC, namely prematurity and neonatal asphyxia, but they also recognized the independent effect of maternal diabetes mellitus. They explored the link between NHC and maternal/neonatal hypomagnesemia, and finally conducted a - randomized controlled trial that demonstrated the ability to prevent NHC by administration of magnesium sulfate soon after birth. CONCLUSION: The PPG in its various phases revealed the important role that Magnesium plays in the regulation of mineral metabolism in pregnancy and, in particular, in pregnancies complicated by pre-gestational diabetes. .

RESUMO

OBJECTIVE: To review how the Cincinnati Diabetes in Pregnancy Program Project Grant (PPG) contributed to understanding and treatment of neonatal complications in infants of diabetic mothers (IDMs) Study Design: Retrospective review of all PPG work on glycemic control at different pregnancy timepoints and its association with embryonic, fetal and neonatal complications, such as congenital malformations (CMs), intrauterine growth restriction (IUGR), macrosomia, hypoglycemia, respiratory distress syndrome (RDS), asphyxia and polycythemia. RESULTS: we found that maternal vasculopathy and poor glycemic control during embryogenesis, but not frequency of maternal hypoglycemic episodes or insulin therapy, are independent risk factors for major CMs. A suggestive association of major CMs with maternal Magnesium deficiency was also observed. Poor glycemic control during late embryogenesis and early fetal development was associated with an increased risk of minor CMs. We described a biphasic pattern of fetal growth; whereby early growth delay was followed by enhanced fetal growth which was associated with neonatal macrosomia. Macrosomia was associated with poorer glycemic control in the third trimester and an increased risk of birth trauma. Macrosomia was also correlated with animal-origin insulin concentrations in cord blood, demonstrating that insulin bound to antibodies can cross the placenta and may affect the fetus. We also showed that neonatal hypoglycemia was significantly associated with third trimester glycemic control, in addition to hyperglycemia occurring during labor. With modern management and adequate prenatal care, IDMs are no longer at increased risk for RDS. Perinatal asphyxia was associated with increased proteinuria appearing in pregnancy, maternal hyperglycemia before delivery, and prematurity. Polycythemia in IDMs is prevalent and correlates with proxy measurements of fetal hypoxemia (nucleated red blood cells at delivery) and poorer glycemic control in late pregnancy. CONCLUSION: The PPG in its various phases revealed the important role of glycemic control at nearly every stage of pregnancy including labor.

RESUMO

Objective: Rates of mother's own milk (MOM) provision in the neonatal intensive care unit (NICU) vary widely, despite acceptance as the gold standard for nutrition in preterm infants. Direct breastfeeding (DBF) supports long-term provision of MOM, but factors that support DBF in preterm infants are unknown. The purpose of this study was to identify factors that predict DBF at oral feeding initiation and at NICU discharge. Methods: This was a retrospective cohort study of preterm infants born at ≤ 32 weeks who were receiving MOM at 32 weeks corrected gestational age (cohort 1) and at discharge to home (cohort 2). The primary outcomes were rates of DBF at oral feeding initiation (cohort 1) and at hospital discharge (cohort 2). We examined bivariate associations between infant characteristics, maternal sociodemographic factors, and hospital practices (e.g., lactation visit timing and frequency) with DBF outcomes and then built logistic regression models to determine the adjusted odds ratio and 95% confidence interval ([adjusted odds ratio [aOR] [95%CI]) for independent predictors of the DBF outcomes. Results: Sixty-four percent of eligible infants initiated DBF, and 51% were DBF at discharge. Sociodemographic, NICU, and lactation support factors were associated with both outcomes. Post hoc analysis showed that similar factors also influenced lactation support provision. Conclusions: Lactation support, NICU and sociodemographic variables influence DBF initiation and DBF at discharge. Interventions that optimize efficient use of available lactation support, address bias, and provide ample opportunity for DBF practice could improve rates.

RESUMO

OBJECTIVES: (1) Assess whether health-related social needs (HRSN)/caregiver mental health concerns (CMHC) disclosure rates differ when screening questions are administered on paper versus electronic tablet. (2) Evaluate whether changes in need identification alters referral rates to social work and our medical-legal partnership (MLP). METHODS: We conducted a retrospective review of HRSN/CMHC screening in publicly insured patients 0-18 years presenting for well-child visits in three primary care practices. Our primary outcome was HRSN/CMHC disclosure rate, comparing the proportion of positive HRSN/CMHC screens during the 11 months before and after screening modality change. Generalized estimating equations and interrupted time series (ITS) were used to assess changes over time. Mediation analyses assessed the indirect effect of HRSN/CMHC disclosure during the electronic screening period on changes in referrals to social work/MLP. RESULTS: A total of 16,151 patients had paper-based HRSN/CMHC screens; 13,019 patients had electronic screens. Overall, 11% of paper-based screens identified ≥1 need, compared to 26% of electronic screens (p<0.001). All three practices saw an increase in disclosure rate after transition from paper to electronic screening (odds ratio [OR] range 1.54 to 4.24). Using ITS, two of three practices had significantly increased odds of need disclosure with electronic screens compared to paper (OR 3.0, 95% confidence interval [CI] 2.5, 3.6; and OR 1.7, 95%CI 1.2, 2.4). Increased HRSN/CMHC disclosure rates from transitioning to electronic screening mediated increased referrals to social work/MLP. CONCLUSIONS: Electronic screening was associated with an increased HRSN/CMHC disclosure rate compared to paper, which led to increased referrals to social work/MLP.

RESUMO

OBJECTIVE: To evaluate the efficacy of Resident Education And Counseling on Household (REACH) Firearm Safety, a novel virtual reality (VR) intervention. METHODS: We conducted a single-center, randomized controlled trial among pediatric residents in a Midwestern academic primary care center comparing REACH Firearm Safety with didactic training (intervention) to didactic training alone (control). In the intervention arm, participants practiced firearm safety counseling with virtual characters and received immediate feedback. All residents completed audio-recorded standardized patient (SP) encounters before and after the training as well as a retrospective pre-post survey. Two reviewers, blinded to allocation arm, used a standardized assessment tool to generate performance scores. Outcomes of interest included the difference between groups in SP performance scores and self-reported confidence. RESULTS: From March to July 2023, 62% of eligible pediatric residents (n=47/76) completed the allocated study tasks (Intervention 19, Control 28). In both groups, SP performance scores and self-reported confidence improved. Compared to the control group, the intervention group demonstrated improvement in sharing information on secure storage devices (p=0.009) and increased confidence on providing information on secure storage (p=0.002). CONCLUSION: Compared with didactic training alone, a VR intervention using deliberate practice improved residents' skills and confidence related to firearm safety counseling.

RESUMO

OBJECTIVE: To evaluate the proximal effects of hypertensive disorders of pregnancy (HDP) on a validated measure of brain abnormalities in infants born at ≤32 weeks' gestational age (GA) using magnetic resonance imaging at term-equivalent age. STUDY DESIGN: In a multisite prospective cohort study, 395 infants born at ≤32 weeks' GA, underwent 3T magnetic resonance imaging scan between 39 and 44 weeks' postmenstrual age. A single neuroradiologist, blinded to clinical history, evaluated the standardized Kidokoro global brain abnormality score as the primary outcome. We classified infants as HDP-exposed by maternal diagnosis of chronic hypertension, gestational hypertension, pre-eclampsia, or eclampsia. Linear regression analysis identified the independent effects of HDP on infant brain abnormalities, adjusting for histologic chorioamnionitis, maternal smoking, antenatal steroids, magnesium sulfate, and infant sex. Mediation analyses quantified the indirect effect of HDP mediated via impaired intrauterine growth and prematurity and remaining direct effects on brain abnormalities. RESULTS: A total of 170/395 infants (43%) were HDP-exposed. Adjusted multivariable analyses revealed HDP-exposed infants had 27% (95% CI 5%-53%) higher brain abnormality scores than those without HDP exposure (P = .02), primarily driven by increased white matter injury/abnormality scores (P = .01). Mediation analyses showed HDP-induced impaired intrauterine growth significantly (P = .02) contributed to brain abnormality scores (22% of the total effect). CONCLUSIONS: Maternal hypertension independently increased the risk for early brain injury and/or maturational delays in infants born at ≤32 weeks' GA with an indirect effect of 22% resulting from impaired intrauterine growth. Enhanced prevention/treatment of maternal hypertension may mitigate the risk of infant brain abnormalities and potential neurodevelopmental impairments.

RESUMO

OBJECTIVE: Using a structural racism framework, we assessed racial inequities in continuity of care, using the Usual Provider Continuity Index (UPC - the proportion of visits with the provider the patient saw most frequently out of all visits), in a set of large pediatric academic clinics. METHODS: We conducted a retrospective cohort study. Patients 12-24 months seen at three pediatric academic primary care clinics for any visit during October 1-31, 2021 were included. We then reviewed continuity for these patients in the preceding 12 months. Outcomes included each patient's UPC for all visits, and a modified UPC for well child checks only (UPC Well). Covariates included race, ethnicity, insurance, clinic site, age, sex, care management, or seeing a social worker. We evaluated for differences in outcomes using bivariate analyses and multivariable regression models. RESULTS: Our cohort included 356 patients (74% Black, 5% Hispanic, 85% Medicaid, 52% female, median age 15.8 months). The median UPC was 0.33 and median UPC Well was 0.40. Black patients had significantly lower median values for UPC (0.33 Black vs 0.40 non-Black, P < .01) and UPC Well (0.33 Black vs 0.50 non-Black, P < .01). There were similar inequities in continuity rates by insurance and clinic site. In multivariable models, clinic site was the only variable significantly associated with continuity. CONCLUSIONS: Clinic sites serving higher percentages of Black patients had lower rates of continuity. The main driver of racial inequities in continuity rates was at the institutional level.

RESUMO

Purpose: Our goal was to evaluate the impact of enumerated antibullying laws and local interventions on school affirmation, risk of physical threat or harm, and suicide attempts for lesbian, gay, bisexual, transgender, and questioning (LGBTQ) youth. Methods: This study used cross-sectional data from three national sources that provided outcomes and potential predictors: (1) The Trevor Project National Survey 2022: based on the LGBTQ youth report, (2) Movement Advancement Project: presence of LGBTQ enumerated antibullying state laws, and (3) School Health Profiles 2020: statewide prevalence of school-level strategies to improve student wellness reported by school personnel. Bivariate and multivariable logistic regression models calculated the relative risks (RRs) for each outcome. Results: LGBTQ youth (n = 27,697) were surveyed. Youth were less likely to identify their school as nonaffirming in states with enumerated laws (RR: 0.97, confidence interval [CI]: 0.94-0.99) and in states with higher percentages of gay/straight alliances (GSAs) (RR: 0.97, 95% CI: 0.96-0.97). Youth were less likely to report a history of physical threat or harm in states with more GSAs (RR: 0.96, 95% CI: 0.95-0.97). Enumerated state laws were associated with a lower risk of suicide attempts among LGBTQ youth (RR: 0.82, 95% CI: 0.77-0.87). Universal strategies/policies not specific to LGBTQ youth did not reduce risk of physical threat/harm or suicide attempts. Conclusions: Statewide enumerated antibullying protections and the presence of a GSA were associated with a decreased risk of poor outcomes among LGBTQ youth. Longitudinal studies are needed to assess the impact of recent legislative changes.

RESUMO

OBJECTIVE: To evaluate factors associated with borderline/clinical range Child Behavior Checklist (CBCL) scores in opioid-exposed children. STUDY DESIGN: Retrospective study of 94 children with prenatal opioid exposure evaluated with the CBCL at age 2 years. RESULTS: Twenty-eight children (30%) had borderline/clinical findings on the CBCL, with 27% scoring borderline/clinical for Externalizing Problems. In the multivariable model, lower Bayley-III motor scores and discharge home with mother with safety plan were associated with borderline/clinical Externalizing Problems. Medication treatment for neonatal opioid withdrawal syndrome (NOWS) was associated with normal Externalizing Problems scores. Treatment with clonidine or phenobarbital was associated with scores in the normal range in all broadband CBCL measures. CONCLUSION: Specific factors are associated with behavioral and emotional challenges measured by borderline/clinical CBCL scores among opioid-exposed children.

RESUMO

BACKGROUND: Inulin-type fructans (ITF) are the leading prebiotics in the market. Available evidence provides conflicting results regarding the beneficial effects of ITF on cardiovascular disease risk factors. OBJECTIVES: This study aimed to evaluate the effects of ITF supplementation on cardiovascular disease risk factors in adults. METHODS: We searched MEDLINE, EMBASE, Emcare, AMED, CINAHL, and the Cochrane Library databases from inception through May 15, 2022. Eligible randomized controlled trials (RCTs) administered ITF or placebo (for example, control, foods, diets) to adults for ≥2 weeks and reported one or more of the following: low, very-low, or high-density lipoprotein cholesterol (LDL-C, VLDL-C, HDL-C); total cholesterol; apolipoprotein A1 or B; triglycerides; fasting blood glucose; body mass index; body weight; waist circumference; waist-to-hip ratio; systolic or diastolic blood pressure; or hemoglobin A1c. Two reviewers independently and in duplicate screened studies, extracted data, and assessed risk of bias. We pooled data using random-effects model, and assessed the certainty of evidence (CoE) using the Grading of Recommendations, Assessment, Development and Evaluation approach. RESULTS: We identified 1767 studies and included 55 RCTs with 2518 participants in meta-analyses. The pooled estimate showed that ITF supplementation reduced LDL-C [mean difference (MD) -0.14 mmol/L, 95% confidence interval (95% CI: -0.24, -0.05), 38 RCTs, 1879 participants, very low CoE], triglycerides (MD -0.06 mmol/L, 95% CI: -0.12, -0.01, 40 RCTs, 1732 participants, low CoE), and body weight (MD -0.97 kg, 95% CI: -1.28, -0.66, 36 RCTs, 1672 participants, low CoE) but little to no significant effect on other cardiovascular disease risk factors. The effects were larger when study duration was ≥6 weeks and in pre-obese and obese participants. CONCLUSION: ITF may reduce low-density lipoprotein, triglycerides, and body weight. However, due to low to very low CoE, further well-designed and executed trials are needed to confirm these effects. PROSPERO REGISTRATION NUMBER: CRD42019136745.

RESUMO

Importance: Dysfunctional patterns of behavior during infancy can predict the emergence of mental health disorders later in childhood. The Baby Pediatric Symptom Checklist (BPSC) can identify indicators of behavioral disorders among children aged 0 to 18 months. Understanding the association of early health-related social needs (HRSNs) with poor infant behavioral functioning can inform interventions to promote early childhood mental well-being. Objective: To examine the association between household HRSNs in the first 4 months of life and BPSC results at 6 months. Design, Setting, and Participants: This was a retrospective cohort analysis of longitudinal electronic health record data. Covariates were selected based on the biopsychosocial ecological model. Logistic regression analyses examined the association of HRSN domains and the number of HRSNs with the 6-month BPSC outcomes. Participants were recruited from 6 primary care clinics within 1 health system. Children aged 5 to 8 months who were evaluated for 6-month well-child visits between March 30, 2021, and June 30, 2022, were included in the study. Exposure: Responses to the first HRSN screening tool that a caregiver completed for infants between 0 and 4 months of age. HRSN domains were examined individually and as the number of positive HRSNs. Main Outcome and Measures: BPSC screen identified for clinical review due to 1 or more elevated subscales (inflexibility, irritability, and difficulty with routines) at 6 months. Results: A total of 1541 children (mean [SD] age, 6.1 [0.5] months; 775 female [50.3%]) were included in the study. A total of 405 children (26.3%) had a BPSC screen identified for clinical review, and 328 caregivers (21.3%) reported at least 1 HRSN. Food insecurity (174 [11.3%]) and benefits issues (169 [11.0%]) were the most frequently reported HRSN. Children in households with food insecurity had statistically significant higher odds of inflexibility (adjusted odds ratio [aOR], 1.73; 95% CI, 1.14-2.63), difficulty with routines (aOR, 1.64; 95% CI, 1.05-2.57), and irritability (aOR, 1.86; 95% CI, 1.13-3.08) than children in households without food insecurity. Children in households with benefits issues had statistically significant higher odds of difficulty with routines (aOR, 1.70; 95% CI, 1.10-2.65) and irritability (aOR, 1.70; 95% CI, 1.03-2.82). Children in households with 2 or more HRSNs had consistently higher odds of having a BPSC screen identified for clinical review (aOR, 2.16; 95% CI, 1.38-3.39) compared with children with no HRSNs. Conclusions and Relevance: Results of this cohort study suggest that household food insecurity, benefits issues, and the number of HRSNs were significantly associated with a BPSC screen identified for clinical review at 6 months of age. These findings highlight the urgency of intervening on HRSNs in the newborn period to prevent adverse infant behavioral outcomes.

RESUMO

Preconception counseling is recommended for all women with diabetes starting at puberty to convey the importance of optimal diabetes management for maternal and fetal outcomes. This study included 622 female participants from the SEARCH for Diabetes in Youth study with a mean age of 22.2 years (range 14-35 years). Only 53.7% reported ever receiving preconception counseling, which was significantly lower among women seeing pediatric providers than those seeing adult or all-age providers. Older age and history of prior pregnancy were associated with increased odds of reporting having received preconception counseling. Identification of barriers to delivering preconception counseling to young females with diabetes and strategies to overcome them are needed to reduce the risk for pregnancy complications and adverse offspring health outcomes.

RESUMO

OBJECTIVE: To investigate the association between exposure to surgery under general anesthesia and brain abnormalities and neurodevelopmental outcomes in very preterm infants. STUDY DESIGN: This prospective observational study includes 392 infants born at or below 32 weeks' gestational age. Participants completed brain MRI at term-equivalent age and Bayley-III assessment at 2 years corrected age. We evaluated the independent effects of surgery on brain MRI abnormalities and neurodevelopmental outcomes after propensity score matching. RESULTS: All infants completed brain MRI, and 341 (87%) completed neurodevelopmental testing. Forty-five received surgery. Surgery was associated with worse MRI abnormalities (p < 0.0001) but with none of the developmental outcomes after propensity score matching. The global brain abnormality score was associated with the Bayley Cognitive (p = 0.005) and Motor (p = 0.028) composite scores. CONCLUSIONS: Very preterm infants exposed to surgery under general anesthesia were at higher risk of brain abnormalities on MRI at term.

RESUMO

BACKGROUND: Diabetes affects millions of people worldwide with a continued increase in incidence occurring within the pediatric population. The potential contribution of persistent organic pollutants (POPs) to diabetes in youth remains poorly known, especially regarding type 1 diabetes (T1D), generally the most prevalent form of diabetes in youth. OBJECTIVES: We investigated the associations between POPs and T1D in youth and studied the impacts of POPs on pancreatic ß-cell function and viability in vitro. METHODS: We used data and plasma samples from the SEARCH for Diabetes in Youth Case Control Study (SEARCH-CC). Participants were categorized as Controls, T1D with normal insulin sensitivity (T1D/IS), and T1D with insulin resistance (T1D/IR). We assessed plasma concentrations of polychlorinated biphenyls (PCBs) and organochlorine pesticides and estimated the odds of T1D through multivariable logistic regression. In addition, we performed in vitro experiments with the INS-1E pancreatic ß-cells. Cells were treated with PCB-153 or p,p'-DDE at environmentally relevant doses. We measured insulin production and secretion and assessed the mRNA expression of key regulators involved in insulin synthesis (Ins1, Ins2, Pdx1, Mafa, Pcsk1/3, and Pcsk2), glucose sensing (Slc2a2 and Gck), and insulin secretion (Abcc8, Kcnj11, Cacna1d, Cacna1b, Stx1a, Snap25, and Sytl4). Finally, we assessed the effects of PCB-153 and p,p'-DDE on ß-cell viability. RESULTS: Among 442 youths, 112 were controls, 182 were classified with T1D/IS and 148 with T1D/IR. The odds ratios (OR) of T1D/IS versus controls were statistically significant for p,p'-DDE (OR 2.0, 95% confidence interval (CI) 1.0, 3.8 and 2.4, 95% CI 1.2, 5.0 for 2nd and 3rd tertiles, respectively), trans-nonachlor (OR 2.5, 95% CI 1.3, 5.0 and OR 2.3, 95% CI 1.1, 5.1 for 2nd and 3rd tertiles, respectively), and PCB-153 (OR 2.3, 95% CI 1.1, 4.6 for 3rd tertile). However, these associations were not observed in participants with T1D/IR. At an experimental level, treatment with p,p'-DDE or PCB-153, at concentrations ranging from 1 × 10-15 M to 5 × 10-6 M, impaired the ability of pancreatic ß-cells to produce and secrete insulin in response to glucose. These failures were paralleled by impaired Ins1 and Ins2 mRNA expression. In addition, among different targeted genes, PCB-153 significantly reduced Slc2a2 and Gck mRNA expression whereas p,p'-DDE mainly affected Abcc8 and Kcnj11. While treatment with PCB-153 or p,p'-DDE for 2 days did not affect ß-cell viability, longer treatment progressively killed the ß-cells. CONCLUSION: These results support a potential role of POPs in T1D etiology and demonstrate a high sensitivity of pancreatic ß-cells to POPs.

RESUMO

We investigate the spatiotemporal dynamics and control of an epidemic using a partial differential equation (PDE) based Susceptible-Latent-Infected-Recovered (SLIR) model. We first validate the model using empirical COVID-19 data corresponding to a period of 45 days from the state of Ohio, United States. Upon optimizing the model parameters in the learning phase of the analysis using actual infection data from a period of the first 30 days, we then find that the model output closely tracks the actual data for the next 15 days. Next, we introduce a control input into the model to represent the Non-Pharmaceutical Intervention of social distancing. Implementing the control using two distinct schemes, we find that in both cases the control input is able to significantly mitigate the infection spread. In addition to opening a novel pathway towards the characterization, analysis and implementation of Non-Pharmaceutical Interventions across multiple geographical scales using Control frameworks, our results highlight the importance of first-principles based PDE models in understanding the spatiotemporal dynamics of epidemics triggered by novel pathogens.

RESUMO

Exposure to maternal diabetes in utero increases the risk in the offspring for a range of metabolic disturbances. However, the timing and variability of in utero hyperglycemic exposure necessary to cause impairment have not been elucidated. The TEAM Study was initiated to evaluate young adult offspring of mothers with pregestational diabetes mellitus. This paper outlines the unique enrollment challenges of the TEAM Study and preliminary analysis of the association between exposure to diabetes in pregnancy and adverse metabolic outcomes. The TEAM Study enrolls offspring of women who participated in a Diabetes in Pregnancy (DiP) Program Project Grant between 1978 and 1995. The DiP Study collected medical and obstetric data across pregnancy. The first 96 eligible offspring of women with pregestational diabetes were age-, sex-, and race-matched to adults from the National Health and Nutrition Examination Survey (NHANES) 2015-2016 with an OGTT. Descriptive and regression analyses were employed to compare TEAM participants to NHANES participants. Among a subset of TEAM participants, we compared the metabolic outcomes across maternal glucose profiles using a longitudinal data clustering technique that characterizes level and variability, in maternal glucose across pregnancy. By comparing categories of BMI, TEAM Study participants had over 2.0 times the odds of being obese compared to matched NHANES participants (for class III obesity, OR = 2.81; 95% confidence interval (CI): 1.15, 6.87). Increasing levels of two-hour glucose were also associated with in utero exposure to pregestational diabetes in matched analyses. Exposure to pregestational diabetes in utero may be associated with an increased risk of metabolic impairment in the offspring with clinical implications.

RESUMO

OBJECTIVE: To identify correlates of hemoglobin A1c (HbA1c) testing frequency and associations with HbA1c levels and microvascular complications in youth-onset diabetes. RESEARCH DESIGN AND METHODS: The SEARCH for Diabetes in Youth study collected data from individuals diagnosed with diabetes before age 20 at 8 years (n=1,885 type 1, n=230 type 2) and 13 years (n=649 type 1, n = 84 type 2) diabetes duration. We identified correlates of reporting ≥3 HbA1c tests/year using logistic regression. We examined associations of HbA1c testing with HbA1c levels and microvascular complications (retinopathy, neuropathy, or nephropathy) using sequentially adjusted linear and logistic regression. RESULTS: For type 1 diabetes, odds of reporting ≥3 HbA1c tests/year at 8 and 13 years diabetes duration decreased with older age at diagnosis (odds ratio [OR] 0.91 [95% CI 0.88-0.95]), longer duration of diabetes (OR 0.90 [0.82-0.99]), not having a personal doctor (OR 0.44 [0.30-0.65]), and lapses in health insurance (OR 0.51 [0.27-0.96]). HbA1c testing ≥3 times/year over time was associated with lower HbA1c levels (OR -0.36% [-0.65 to -0.06]) and lower odds of microvascular complications (OR 0.64 [0.43-0.97]) at 13 years duration, but associations were attenuated after adjustment for HbA1c testing correlates (OR -0.17 [-0.46 to 0.13] and 0.70 [0.46-1.07], respectively). For type 2 diabetes, not seeing an endocrinologist decreased the odds of reporting ≥3 HbA1c tests/year over time (OR 0.19 [0.06-0.63]), but HbA1c testing frequency was not associated with HbA1c levels or microvascular complications. CONCLUSIONS: We observed disparities in HbA1c testing frequency predominately by health care-related factors, which were associated with diabetes outcomes in type 1 diabetes.

RESUMO

OBJECTIVE: To examine the incidence of postoperative neonatal acute kidney injury (AKI) following general surgical procedures and to test the hypothesis that postoperative urine neutrophil gelatinase-associated lipocalin (uNGAL) concentrations predict AKI. The secondary objective was to evaluate for an association between AKI and hospital mortality. STUDY DESIGN: Prospective observational study of infants undergoing abdominal and thoracic surgical procedures in the neonatal intensive care unit from October 2018 to March 2020. The primary outcome was incidence of neonatal AKI (defined by the neonatal modified Kidney Diseases Improving Global Outcomes criteria) following each procedure to postoperative day 5. Severe AKI was defined as stage 2 or 3 AKI. Urine samples were obtained pre- and postoperatively at 6 time points to evaluate for levels of uNGAL. Secondary outcomes were in-hospital mortality and length of stay. RESULTS: Subjects (n = 141) underwent a total of 192 general surgical procedures during the study period. Neonatal AKI and severe AKI occurred following 36 (18%) and 15 (8%) procedures (n = 33 subjects). Percent change of uNGAL from 24 hours preoperatively to 24 hours postoperatively was greater in subjects with neonatal AKI (190.2% [IQR 0.0, 1666.7%] vs 0.7% [IQR -31.2%,140.2%], P = .0374). The strongest association of uNGAL and AKI occurred at 24 hours postoperatively (area under the receiver operator curves of 0.81, 95% CI 0.72, 0.89). Increased mortality risk was observed in subjects with any postoperative AKI (aOR 11.1 95% CI 2.0, 62.8, P = .0063) and severe AKI (aOR 13.8; 95% CI 3.0, 63.1, P = .0007). CONCLUSION: Elevation in uNGAL 24 hours postoperative was associated with AKI. Neonates with postoperative AKI had increased mortality.

RESUMO

OBJECTIVE: Over the past few decades, life expectancy in Brazil has increased from 48 years in 1950s to 76 years in 2017. The aim of this study was to investigate the impact of ageing on: (1) the frequency of hospitalisations due to bloodstream infection (BSI); (2) the incidence of hospital-acquired BSI (H-BSI); (3) the incidence of BSI caused by multidrug-resistant (MDR) agents and (4) the mortality rate of BSI in a public hospital. METHODS: A hospital-based case-cohort study was conducted between 1 December 2013 and 31 December 2015. The data were analysed using multivariable logistic regression. RESULTS: A total of 500 BSI episodes were detected, among 11,102 hospitalizations. The incidence of hospitalisations resulting from BSI was significantly higher in older than younger patients (3.7/100 vs. 2.0/100, p < 0.01). Similarly, the incidence of hospital-acquired BSI was significantly higher in older patients (2.7/100 vs. 0.9/100, p < 0.01). Klebsiella pneumoniae (15.9%), Staphylococcus aureus (14.3%), Escherichia coli (13.1%) and Acinetobacter spp. (12.1%) were the most common agents isolated. MDR agents caused 37.6% of the BSI episodes; enteric Gram-negative bacilli resistant to third- or fourth-generation cephalosporins (9.7%) and carbapenem-resistant Acinetobacter spp. (9.2%) were the most common MDR agents. The following complications were independently associated with ageing: Charlson comorbidity index (OR = 1.16; 95% CI = 1.09-1.24); BSI secondary to urinary tract infection (OR = 2.14; 95% CI = 1.29-3.55); BSI secondary to pneumonia (OR = 1.77; 95% CI = 1.07-2.93) and 30-day mortality following BSI (OR = 2.19; 95% CI = 1.43-3.36). CONCLUSIONS: These data suggest ageing has a significant impact on hospitalisations due to BSI, H-BSI incidence and mortality from BSI in older patients attending a Brazilian public hospital. Age was not significantly associated with MDR-related BSI. These results indicate that age plays an important role in the increase in morbidities and mortality resulting from BSI in Brazil and that with the increased life expectancy observed over recent decades in Brazil, the burden of BSI will be expected to continue to increase. This dynamic needs to be better understood with additional studies.

RESUMO

BACKGROUND: Although donor milk is increasingly fed to preterm infants, the resultant quality of growth and body composition is unknown. The aim of this pilot study was to describe the body composition of very low-birth-weight infants fed human milk in the neonatal intensive care unit and explore the association between the proportion of donor human milk intake and fat-free and fat mass deposition. METHODS: Body composition of 30 preterm infants fed maternal and donor human milk was measured by air displacement plethysmography. Regression models were developed to associate each parameter of body composition with the proportion of donor milk intake and other explanatory variables. RESULTS: The proportion of donor milk intake was negatively associated with body fat percentage (P = .01). Fat-free mass z-scores ranged from -4.6 to 1.11 (mean z-score of -0.95, 17th percentile). CONCLUSION: Donor human milk intake is negatively associated with body fat percentage in this pilot study of very low-birth-weight preterm infants.
