RESUMO
The primary hyperoxalurias (PH 1, 2, and 3) are rare autosomal recessive disorders of glyoxylate metabolism resulting in hepatic overproduction of oxalate. Clinical presentations that should prompt consideration of PH include kidney stones, nephrocalcinosis, and kidney failure of unknown etiology, especially with echogenic kidneys on ultrasound. PH1 is the most common and severe of the primary hyperoxalurias with a high incidence of kidney failure as early as infancy. Until the recent availability of a novel RNA interference (RNAi) agent, PH care was largely supportive of eventual need for kidney/liver transplantation in PH1 and PH2. Together with the Oxalosis and Hyperoxaluria Foundation, the authors developed a diagnostic algorithm for PH1 and in this report outline best clinical practices related to its early diagnosis, supportive treatment, and long-term management, including the use of the novel RNAi. PH1-focused approaches to dialysis and kidney/liver transplantation for PH patients with progression to chronic kidney disease/kidney failure and systemic oxalosis are suggested. Therapeutic advances for this devastating disease heighten the importance of early diagnosis and informed treatment.
RESUMO
This study aimed to examine the associations between child temperament and trajectories of the three dimensions of the student-teacher relationship (Closeness, Conflict, and Dependency) during elementary school. Latent class growth analyses conducted among 744 French-Canadian students recruited between 2008 and 2010 (46.8% girls; Mage = 8.39; 90.9% White; 49.7% with externalizing behavior problems) revealed four Closeness trajectories and three Conflict trajectories, but no significant variability between children in mean levels of change in Dependency. Surgency-Extraversion and Effortful control were associated with specific trajectories of Closeness and Conflict. Effortful control was also associated with cross-sectional assessments of Dependency. These results suggest that temperament is a useful construct in understanding developmental patterns of the student-teacher relationship across the elementary school years.
RESUMO
BACKGROUND: In the context of increased media use and family distress during the pandemic, we examine whether preschooler screen time at age 3.5 contributes to later expressions of anger/frustration at 4.5, while also considering the inverse association. METHODS: Data are from a cohort of 315 Canadian preschool-aged children during the COVID-19 pandemic. Parent-reported measures included child h/day of screen time and child temperamental anger/frustration, both measured at 3.5 and 4.5 years of age. Indicators of family distress include use of childcare and child sleep, family income, parenting stress, and parent education, marital and employment status. We also consider child sex as a control variable. RESULTS: A crossed-lagged panel model revealed continuity in screen time between the ages of 3.5 and 4.5 (ß = 0.68) and temperamental anger/frustration from 3.5 to 4.5 (ß = 0.60). Child screen time at age 3.5 predicted increased proneness to anger/frustration at age 4.5 (ß = 0.14). Anger/frustration at age 3.5 did not predict screen time at age 4.5. CONCLUSION: Our results suggest that preschooler screen time during the pandemic may have undermined the ability to regulate negative emotions, a key component of social and academic competence. Supporting parents in implementing healthy media habits post pandemic may benefit young children's development. IMPACT: Key message: this study observes prospective bidirectional associations between preschoolers screen time and temperamental displays of anger or frustration during the COVID-19 pandemic. What does it add: we provide evidence that preschool screen time at age 3.5 prospectively contributes to the tendency to react in anger/frustration at age 4.5. In contrast, greater proneness to anger/frustration did not predict later exposure to screen time. What is the impact: health practitioners should enquire about media use habits during well-child visits to foster children's healthy development during the preschool years.

Childhood intimate partner violence (IPV) exposure increases the likelihood of internalizing and externalizing problems. There is substantial variability in children's outcomes following IPV exposure, but the reasons behind this are unclear, particularly among preschool-age children. The current study aimed to examine the direct and indirect effects of IPV on preschoolers' mental health through parent factors (parenting and parental depression), exploring child temperament as a potential moderator of the relation between IPV and child outcomes. Participants were 186 children (85 girls) and their parents living in the United States. Data were initially collected when children were age three, with follow-up at ages four and six. Both parents' baseline IPV perpetration had adverse effects on child outcomes. Mothers' IPV was associated with greater paternal depression, paternal overractivity, and maternal laxness, whereas fathers' IPV was associated with more paternal overreactivity. Only paternal depression mediated the effect of mothers' IPV on child outcomes. Parenting did not mediate nor did child temperament moderate the relation between IPV and child outcomes. Results shed insight into the need to address parental mental health in families experiencing IPV and underline the need for a further exploration of individual- and family-level mechanisms of adjustment following IPV exposure.
RESUMO
This study examined racial/ethnic differences in the relations between three dimensions of parenting practices (harsh, lax, and warm parenting) and children's externalizing behaviors across European American, African American, and Latinx families. Participants included 221 mothers who identified as African American (n = 32), Latina (n = 46), or European American (n = 143). Mothers' self-rated and observer-coded harshness, laxness, and warmth, and their ratings of their 3-year-old children's externalizing behaviors (hyperactivity, aggression) were analyzed. Multiple regression analyses indicated some racial/ethnic differences in the relations between harsh and warm parenting, and children's externalizing behaviors. The slopes of the relation between greater harshness and greater aggression and hyperactivity were more positive for European American families than for African American or Latinx families. The slopes of the relation between greater warmth and less aggression were more negative for European American and Latinx families than for African American families. Results indicated no racial/ethnic differences in the relation between laxness and externalizing behaviors. These findings suggest racial/ethnic differences in the relation between some parenting practices and externalizing behaviors, which has important implications in culturally sensitive clinical practice for different racial/ethnic groups. More research is necessary to replicate these findings, and to identify other parenting practices that may be more important in racial/ethnic minority families.

Worldwide, peritoneal dialysis (PD) is the preferred renal replacement therapy option for children with end-stage renal disease who are awaiting transplantation. PD involves the instillation of a specifically formulated solution into the peritoneal cavity via a PD catheter, with two-way exchange of solutes and waste products along a concentration gradient. This exchange occurs across the peritoneal membrane. The PD catheter has intraperitoneal, abdominal wall, and external components. Enormous efforts have been directed to augment the efficiency and longevity of the peritoneum as a dialysis system by preventing PD-related infectious and noninfectious complications, which may otherwise result in technique failure and a subsequent temporary or permanent switch to hemodialysis. Imaging has an instrumental role in prompt diagnosis of PD complications and in guiding the management of these complications. The main imaging techniques used in the setting of PD complications-namely, conventional radiography, US, CT, MRI, and peritoneal scintigraphy-as well as the benefits and limitations of these modalities are reviewed. The authors also describe the frequently encountered radiologic findings of each complication. Familiarity with these features enables the radiologist to play a crucial role in early diagnosis of PD complications and aids the pediatric nephrologist in tailoring or discontinuing PD and transitioning to hemodialysis if necessary.

INTRODUCTION: Gordonia species, aerobic, weakly acid-fast, Gram-positive bacilli, are a rare cause of peritonitis in patients undergoing peritoneal dialysis (PD). We report the first pediatric case of PD-related peritonitis caused by Gordonia bronchialis. CASE PRESENTATION: A 13-year-old girl with chronic kidney disease (CKD) stage 5D, on continuous cycling PD (CCPD) for 8 years, presented with cloudy PD effluent, with no abdominal discomfort or fever. Intra-peritoneal (IP) loading doses of vancomycin and ceftazidime were started at home after obtaining a PD effluent sample, which showed WBC 2,340 × 10 /L (59% neutrophils) and Gram-positive bacilli. On admission, she was clinically well and afebrile, with no history of methicillin-resistant Staphylococcus aureus (MRSA) infection, so vancomycin was discontinued, and IP ceftazidime and cefazolin were started, following a loading dose of intravenous cefazolin. Gordonia species grew after 5 days of incubation and later identified as Gordonia bronchialis. IP vancomycin was restarted as monotherapy, empirically for a total of 3 weeks therapy. A 2-week course of oral ciprofloxacin was added, based on susceptibility testing. PD catheter replacement was advised due to the risk of recurrence but was refused. A relapse occurred 16 days after discontinuing antibiotics, successfully treated with a 2-week course of IP ceftazidime and vancomycin. The PD catheter was removed and hemodialysis initiated. She received a further 2-week course of oral ciprofloxacin and amoxicillin-clavulanate post PD catheter removal. CONCLUSIONS: Gordonia bronchialis is an emerging pathogen in PD peritonitis and appears to be associated with a high risk of relapse. PD catheter replacement is strongly suggested.

BACKGROUND: Intra-dialytic hypotension (IDH) is the most common serious adverse event in paediatric haemodialysis (HD). Repeated IDH results in chronic multi-organ damage and increased mortality. At the Hospital for Sick Children, Toronto, retrospective data from all in-centre HD sessions revealed frequently occurring IDH events (16.5 ± 5.6% of HD sessions per week). Based on literature review and clinical expertise, fluid volume management was selected as a potential modifiable risk factor to decrease IDH. Root causes identified as contributing to IDH were incorporated into a Paediatric haemodialysis fluid volume management (PedHDfluid) program using the Model for Improvement methodology including rapid cycles of change. METHODS: Multiple measures were evaluated including (i) Outcome: IDH events per number of HD sessions per week; (ii) Process: number of changes to estimated dry weight per number of HD sessions per week; (iii) Balancing: time spent on dry weight meeting per week. Data was analysed using statistical process control charts. We aimed to decrease IDH in our dialysis unit to < 10% of HD sessions per week over a 6-month period by implementing a PedHDfluid program, including a multifaceted dry weight assessment protocol, multidisciplinary meetings and electronic health records "Dry Weight Evaluation flow sheet/synopsis". RESULTS: The project resulted in a decline in IDH events from 16.5 ± 5.6% to 8.8 ± 3.3% of HD sessions per week. More frequent dry weight changes and increased awareness of fluid removal goals were noted. CONCLUSIONS: A multidisciplinary approach including regular assessment, guidelines and systematic discussion, with an embedded electronic health record assessment and data gathering tool may sustainably reduce IDH events. A higher resolution version of the Graphical abstract is available as Supplementary information.

PURPOSE: The considerable volume of infections from SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), has made it challenging for health departments to collect complete data for national disease reporting. We sought to examine sensitivity of the COVID-19 case report form (CRF) pregnancy field by comparing CRF data to the gold standard of CRF data linked to birth and fetal death certificates. DESCRIPTION: CRFs for women aged 15-44 years with laboratory-confirmed SARS-CoV-2 infection were linked to birth and fetal death certificates for pregnancies completed during January 1-December 31, 2020 in Illinois and Tennessee. Among linked records, pregnancy was considered confirmed for women with a SARS-CoV-2 specimen collection date on or prior to the delivery date. Sensitivity of the COVID-19 CRF pregnancy field was calculated by dividing the number of confirmed pregnant women with SARS-CoV-2 infection with pregnancy indicated on the CRF by the number of confirmed pregnant women with SARS-CoV-2 infection. ASSESSMENT: Among 4276 (Illinois) and 2070 (Tennessee) CRFs that linked with a birth or fetal death certificate, CRF pregnancy field sensitivity was 45.3% and 42.1%, respectively. In both states, sensitivity varied significantly by maternal race/ethnicity, insurance, trimester of prenatal care entry, month of specimen collection, and trimester of specimen collection. Sensitivity also varied by maternal education in Illinois but not in Tennessee. CONCLUSION: Sensitivity of the COVID-19 CRF pregnancy field varied by state and demographic factors. To more accurately assess outcomes for pregnant women, jurisdictions might consider utilizing additional data sources and linkages to obtain pregnancy status.

Pregnant women with coronavirus disease 2019 (COVID-19) are at increased risk for severe illness and might be at risk for preterm birth (1-3). The full impact of infection with SARS-CoV-2, the virus that causes COVID-19, in pregnancy is unknown. Public health jurisdictions report information, including pregnancy status, on confirmed and probable COVID-19 cases to CDC through the National Notifiable Diseases Surveillance System.* Through the Surveillance for Emerging Threats to Mothers and Babies Network (SET-NET), 16 jurisdictions collected supplementary information on pregnancy and infant outcomes among 5,252 women with laboratory-confirmed SARS-CoV-2 infection reported during March 29-October 14, 2020. Among 3,912 live births with known gestational age, 12.9% were preterm (<37 weeks), higher than the reported 10.2% among the general U.S. population in 2019 (4). Among 610 infants (21.3%) with reported SARS-CoV-2 test results, perinatal infection was infrequent (2.6%) and occurred primarily among infants whose mother had SARS-CoV-2 infection identified within 1 week of delivery. Because the majority of pregnant women with COVID-19 reported thus far experienced infection in the third trimester, ongoing surveillance is needed to assess effects of infections in early pregnancy, as well the longer-term outcomes of exposed infants. These findings can inform neonatal testing recommendations, clinical practice, and public health action and can be used by health care providers to counsel pregnant women on the risks of SARS-CoV-2 infection, including preterm births. Pregnant women and their household members should follow recommended infection prevention measures, including wearing a mask, social distancing, and frequent handwashing when going out or interacting with others or if there is a person within the household who has had exposure to COVID-19..

BACKGROUND: Outcomes of pediatric intestinal failure (PIF) have improved recently, with other comorbidities, such as increased echogenicity/nephrocalcinosis on ultrasound (US) in long-term survivors now evident. We evaluated the significance of nephrocalcinosis over time in PIF and its impact on renal function. METHODS: Retrospective analysis on a cohort of PIF patients was performed. Presence of nephrocalcinosis and/or increased renal echogenicity (identified on US), estimated glomerular filtration rate (eGFR; mlâ·âminâ·â1.73âm2), renal tubular function, PN volume (mlâ·âkgâ·âday) and PN exposure time (hours/day) were reviewed annually over a follow-up period of 2 years. Outcomes in the nephrocalcinosis versus normal US groups were compared. RESULTS: Forty patients (28 boys, median age 2.7 years) were followed for 2 years. Fifteen (38%) had either increased echogenicity or nephrocalcinosis (group 1) at initial US. US were normal in the remaining 25 (62%) on initial assessment (group 2). eGFR did not differ between group 1 and group 2 at baseline (118 vs 133, Pâ=â0.51) and year 2 (130 vs 131, Pâ=â1.00). The percentage of patients with abnormal markers of tubular function was similar in both groups at year 2 (high urine calcium: creatinine 33 versus 30, Pâ=â0.83; high urine calcium: citrate 39 versus 42, Pâ=â0.87; low urine citrate: creatinine 15 versus 17, Pâ=â1.00; high urine oxalate: creatinine 39 versus 25, Pâ=â0.77). CONCLUSIONS: A large proportion of PIF patients with a history of parenteral nutrition (PN) exposure have nephrocalcinosis and/or increased echogenicity on US. Over a 2-year follow-up period, however, these abnormalities had no impact on eGFR or renal tubular function.

BACKGROUND: This study aimed to evaluate outcome of children on chronic peritoneal dialysis (PD) with a concurrent colostomy. METHODS: Patients were identified through the International Pediatric Peritoneal Dialysis Network (IPPN) registry. Matched controls were randomly selected from the registry. Data were collected through the IPPN database and a survey disseminated to all participating sites. RESULTS: Fifteen centers reported 20 children who received chronic PD with a co-existing colostomy. The most common cause of end stage kidney disease was congenital anomalies of the kidney and urinary tract (n = 16, 80%). The main reason for colostomy placement was anorectal malformation (n = 13, 65%). The median age at colostomy creation and PD catheter (PDC) insertion were 0.1 (IQR, 0-2.2) and 2.8 (IQR 0.2-18.8) months, respectively. The colostomies and PDCs were present together for a median 18 (IQR, 4.9-35.8) months. The median age at PDC placement in 46 controls was 3.4 (IQR, 0.2-7.4) months of age. Fourteen patients (70%) developed 39 episodes of peritonitis. The annualized peritonitis rate was significantly higher in the colostomy group (1.13 vs. 0.70 episodes per patient year; p = 0.02). Predominant causative microorganisms were Staphylococcus aureus (15%) and Pseudomonas aeruginosa (13%). There were 12 exit site infection (ESI) episodes reported exclusively in colostomy patients. Seven colostomy children (35%) died during their course of PD, in two cases due to peritonitis. CONCLUSION: Although feasible in children with a colostomy, chronic PD is associated with an increased risk of peritonitis and mortality. Continued efforts to reduce infection risk for this complex patient population are essential.

OBJECTIVE: Cancer and Aging: Reflections for Elders (CARE) is a novel, telephone-delivered intervention designed to alleviate distress in older cancer patients. This pilot randomized controlled trial tested the feasibility and initial efficacy of CARE, drawing from age-appropriate developmental themes and well-established coping theory. METHOD: Eligible patients were ≥70 years old; ≥6 months post-diagnosis of lung, prostate, breast, lymphoma, or gynecological cancer; on active cancer treatment or within 6 months of ending cancer treatment; and had elevated scores on the Distress Thermometer (≥4) or Hospital Anxiety and Depression Scale (≥6). Participants completed five sessions of psychotherapy over 7 weeks with assessments at study entry, post-intervention, and 2 months post-intervention. Primary outcomes were feasibility and initial efficacy on anxiety and depression; secondary outcomes included demoralization, coping, loneliness, and spiritual well-being. RESULTS: Fifty-nine participants were randomized to either the CARE arm (n = 31) or the enhanced Social Work Control arm (n = 28). The intervention was feasible and tolerable, meeting a priori criteria for rates of eligibility, acceptance, retention, assessment, and treatment fidelity. Upon completion of the intervention, participants in the CARE arm demonstrated lower mean depression scores (d = 0.58 [CI: 0.04-1.12], P = 0.01) and trended towards increased coping-planning (d = 0.30 [CI: -0.83 to 0.24], P = 0.18). Promising trends in anxiety (d = 0.41 [CI: -0.17 to 0.98], P = 0.10) emerged at 2 months post-intervention; effects for coping-planning dissipated. CONCLUSION: These pilot data suggest the CARE intervention is feasibly delivered, potentially impacts important psychosocial variables, and is accessible for older, frail patients with cancer. Future research will evaluate this intervention on a larger scale.

The present study examined the bidirectional relation between family functioning and attention-deficit/hyperactivity disorder (ADHD) symptoms across the preschool years. Participants included 197 (110 boys) 3-year-old children (M = 44.14 months, SD = 3.43; 60% White) with and without behavior problems and their parents who took part in a 3-year longitudinal study. Parenting, parent psychopathology, life stress, and child symptoms were assessed annually from ages 3 to 6. Cross-lagged models provided evidence for both parent and child effects for mothers. In particular, greater maternal overreactive parenting and life stress were predictive of more child ADHD symptoms, and greater child ADHD symptoms significantly predicted greater maternal life stress and depressive symptoms and lower warmth, controlling for child oppositional defiant disorder and parent ADHD symtoms. Child effects were evident for fathers' depression and life stress, but these did not remain controlling for paternal ADHD symptoms. Findings suggest that targeting child ADHD symptoms, maternal overreactive parenting, and maternal stress each hold promise for attenuating the negative mutual influence of child ADHD symptoms and family functioning over time.

The purpose of this study is to examine the psychometric properties of the 18 Diagnostic and Statistical Manual of Mental Disorders (DSM) symptoms of attention deficit/hyperactivity disorder (ADHD) in 2-year-old children. ADHD is typically diagnosed in elementary school, but research suggests that many children with ADHD first show symptoms during the toddler years. An important first step in identifying toddlers who are at high risk for developing ADHD is to better understand the properties of DSM symptoms of ADHD in young children. Parents of 2-year-old children (N = 434; 240 boys, 194 girls; M = 29.07 months, SD = 3.42) across the United States were recruited online through Amazon's Mechanical Turk to complete surveys about their children's ADHD symptoms and temperament. Confirmatory factor analysis showed that 2- and 3-factor models fit well. All but one verbal hyperactive/impulsive symptom loaded highly on their respective factors. Relations between ADHD symptoms and temperament traits provided some support for convergent and divergent validity of the symptoms. Finally, item response theory analyses showed that items showed moderate to high levels of discrimination between toddlers with high and low levels of ADHD symptoms. Psychometric properties in 2-year-old children were generally comparable to those in older children, with similar factor structure, good reliability and validity, and good though somewhat lower discrimination, particularly for verbal symptoms. The study provides support for conducting prospective studies to determine whether these symptoms have utility for identifying at-risk toddlers.

Oppositional defiant disorder (ODD) is a commonly diagnosed childhood behavior disorder, yet knowledge of relations between ODD and early neuropsychological functions, particularly independent of attention deficit/hyperactivity disorder (ADHD), is still limited. In addition, studies have not examined neuropsy chological functioning as it relates to the different ODD symptom dimensions. Structural equation modeling was used to investigate how preschool neuropsychological functioning predicted negative affect, oppositional behavior, and antagonistic behavior symptom dimensions of ODD in 224 six-year-old children, oversampled for early behavior problems. Working memory, inhibition, and sustained attention predicted negative affect symptoms of ODD, controlling for ADHD, whereas delay aversion uniquely predicted oppositional behavior, controlling for ADHD. Delay aversion also marginally predicted antagonistic behavior, controlling for ADHD. Results demonstrate that different ODD symptom dimensions may be differentially predicted by different neuropsychological functions. The findings further underscore the importance of future research on ODD to take into account the possible heterogeneity of both symptoms and underlying neuropsychological functioning.

OBJECTIVES: The rate of severe maternal morbidity in the United States increased approximately 200% during 1993-2014. Few studies have reported on the health of the entire pregnant population, including women at low risk for maternal morbidity. This information might be useful for interventions aimed at primary prevention of pregnancy complications. To better understand this, we sought to describe the distribution of comorbid risk among all delivery hospitalizations in Massachusetts and its association with the distribution of severe maternal morbidity. METHODS: Using an existing algorithm, we assigned an obstetric comorbidity index (OCI) score to delivery hospitalizations contained in the Massachusetts pregnancy to early life longitudinal (PELL) data system during 1998-2013. We identified which hospitalizations included severe maternal morbidity and calculated the rate and frequency of these hospitalizations by OCI score. RESULTS: During 1998-2013, PELL contained 1,185,182 delivery hospitalizations; of these 5325 included severe maternal morbidity. Fifty-eight percent of delivery hospitalizations had an OCI score of zero. The mean OCI score increased from 0.60 in 1998 to 0.82 in 2013. Hospitalizations with an OCI score of zero comprised approximately one-third of all deliveries complicated by severe maternal morbidity, but had the lowest rate of severe maternal morbidity (22.8/10,000 delivery hospitalizations). CONCLUSIONS: The mean OCI score increased during the study period, suggesting that an overall increase in risk factors has occurred in the pregnant population in Massachusetts. Interventions that can make small decreases to the mean OCI score could have a substantial impact on the number of deliveries complicated by severe maternal morbidity. Additionally, all delivery facilities should be prepared for severe complications during low-risk deliveries.

PURPOSE: Pre-pregnancy and post-delivery hospitalizations were compared as markers for health among women who conceived using assisted reproductive technology (ART), non-ART medically assisted reproduction (MAR), no treatment (unassisted subfertile), and who were fertile. METHODS: We analyzed hospital discharge data linked to Massachusetts birth certificates from 2004 to 2013 within 5 years prior to pregnancy and 8-365 days post-delivery. ART deliveries were linked from a national ART database; MAR deliveries had fertility treatment but not ART; unassisted subfertile women had subfertility but no ART or MAR; and fertile women had none of these. Prevalence of diagnoses during hospitalization was quantified. Multivariable logistic regression models with fertile deliveries as reference were adjusted for maternal age, race, education, year, and plurality (post-delivery only) with results reported as adjusted odds ratios (AORs) and 95% confidence intervals (CI). RESULTS: Of 170,605 privately insured, primiparous deliveries, 10,458 were ART, 3005 MAR, 1365 unassisted subfertile, and 155,777 fertile. Pre-pregnancy hospitalization occurred in 6.8% and post-delivery in 2.8% of fertile women. Subfertile groups had more pre-pregnancy hospitalizations (AOR, 95% CI: 1.84, 1.72-1.96 ART; 1.41, 1.24-1.60 MAR; 3.02, 2.62-3.47 unassisted subfertile) with endometriosis, reproductive organ disease, ectopic pregnancy/miscarriage, and disorders of menstruation, ovulation, and genital tract being common. Post-delivery hospitalizations were significantly more frequent in the ART (AOR 1.19, 95% CI 1.05-1.34) and unassisted subfertile (1.59, 1.23-2.07) groups with more digestive tract disorders, thyroid problems, and other grouped chronic disease conditions. CONCLUSIONS: Greater likelihood of hospitalization in the ART, MAR, and unassisted subfertile groups is largely explained by admissions for conditions associated with subfertility.
