Surgical outcomes of pediatric glaucoma in Indian eyes

Abstract Purpose: To evaluate the surgical outcomes of pediatric glaucoma in a cohort of Indian population. Materials and Methods: We conducted a single-center retrospective study including pediatric glaucoma patients who had undergone surgery between January 2012 and January 2022. The surgeries performed were trabeculectomy with mitomycin-C or Ologen, combined trabeculectomy with trabeculotomy (CTT), Ahmed glaucoma valve (AGV) implantation, and diode laser transscleral cyclophotocoagulation. Success was defined as complete if intraocular pressure (IOP) was between 6 and 21 mmHg in children who were examined on slit lamp, or between 6 and 18 mmHg in patients examined under general anesthesia, in the absence of any glaucoma medication and as qualified, with glaucoma medication at the last follow-up. Outcome measures included IOP at the last follow-up, number of glaucoma medications, any complications, and additional surgeries. Results: Seventy-eight eyes of 68 children were included. The most common glaucoma types were primary congenital glaucoma (30.8%), followed by posttraumatic glaucoma (17.9%) and postvitreoretinal surgery glaucoma (16.7%). The mean IOP reduced from 34.17 ± 9.35 mmHg preoperatively to 21.38 ± 9.61 mmHg at the last follow-up (P < 0.001). The number of glaucoma medications reduced from 2.55 ± 1.10 preoperatively to 1.76 ± 1.26 at the last follow-up (P < 0.001). Success was achieved in 62.8% of eyes and the mean survival time was 3.62 years. Among all procedures, AGV implantation had a longer survival time (mean 4.86 years). Conclusion: Pediatric glaucoma management remains a challenge. Majority of the cases remain refractory in spite of multiple surgical interventions. AGV and CTT could be offered as primary surgery in cases of pediatric glaucoma with hazy cornea where goniotomy may not be an option.

Building consensus for the medical management of children with moderate and severe acute spinal cord injury: a modified Delphi study.

The focus of this modified Delphi study was to investigate and build consensus regarding the medical management of children with moderate and severe acute spinal cord injury (SCI) during their initial inpatient hospitalization. This impetus for the study was based on the AANS/CNS guidelines for pediatric SCI published in 2013, which indicated that there was no consensus provided in the literature describing the medical management of pediatric patients with SCIs. An international, multidisciplinary group of 19 physicians, including pediatric neurosurgeons, orthopedic surgeons, and intensivists, were asked to participate. The authors chose to include both complete and incomplete injuries with traumatic as well as iatrogenic etiologies (e.g., spinal deformity surgery, spinal traction, intradural spinal surgery, etc.) due to the overall low incidence of pediatric SCI, potentially similar pathophysiology, and scarce literature exploring whether different etiologies of SCI should be managed differently. An initial survey of current practices was administered, and based on the responses, a follow-up survey of potential consensus statements was distributed. Consensus was defined as ≥ 80% of participants reaching agreement on a 4-point Likert scale (strongly agree, agree, disagree, strongly disagree). A final meeting was held virtually to generate final consensus statements. Following the final Delphi round, 35 statements reached consensus after modification and consolidation of previous statements. Statements were categorized into the following eight sections: inpatient care unit, spinal immobilization, pharmacological management, cardiopulmonary management, venous thromboembolism prophylaxis, genitourinary management, gastrointestinal/nutritional management, and pressure ulcer prophylaxis. All participants stated that they would be willing or somewhat willing to change their practices based on consensus guidelines. General management strategies were similar for both iatrogenic (e.g., spinal deformity, traction, etc.) and traumatic SCIs. Steroids were recommended only for injury after intradural surgery, not after acute traumatic or iatrogenic extradural surgery. Consensus was reached that mean arterial pressure ranges are preferred for blood pressure targets following SCI, with goals between 80 and 90 mm Hg for children at least 6 years of age. Further multicenter study of steroid use following acute neuromonitoring changes was recommended.

Hipertenzija kod dece i adolescenata

Until recently, secondary hypertension used to be the most common form of hypertension in the paediatric population. Due to the increasing prevalence of obesity-related hypertension in children and adolescents, the share of secondary hypertension has decreased from 85% to 9%. Today, primary hypertension has become the dominant form of hypertension in the paediatric population. The purpose of this paper is to show the prevalence of various forms of hypertension and the prevalence of primary hypertension in children and adolescents relative to sex, age and body weight category in the General Hospital "Dr. Laza K. Lazarević" in Šabac. In children with secondary hypertension, the impact of body weight was not assessed since an organic cause of hypertension had been identified in these patients. All children from the age of a new-born to the age of 18 years with a diagnosis of hypertension (International Classification of Diseases, tenth revision (IDC-10), code I10-I15) in the period from 1 January 2013 to 31 December 2022 were selected from the medical digital database. This analysis included all children who showed blood pressure values above 95th percentile for age, sex and height in children under 13 and above 120/80 mmHg in children over 13, upon repeated measurements of blood pressure in the General Hospital, who were presumed to have hypertension. These children were referred to further evaluation at tertiary healthcare institutions, where a diagnosis of hypertension was made. Of the 134 children referred to the General Hospital due to elevated blood pressure levels measured in the primary care physician's office, hypertension was diagnosed in almost one in four subjects (24.6%). Primary hypertension was diagnosed in 18 (54.5%), secondary hypertension in 8 (24.2%) and white coat hypertension in 7 (21.2%) children. Primary hypertension was more common in boys (70.6%) than girls (37.5%). Among children with primary hypertension, overweight and obese children represented 66.7% of the group at the time of diagnosis. Statistical data analysis did not find a statistically significant difference in the prevalence of primary hypertension among the body weight or age categories. Since primary hypertension is the most significant and potentially reversible factor for the development of cardiovascular disease, early detection and treatment of primary hypertension in children is crucial in the prevention of cardiovascular disease in adults.

Prevalence of and Factors Associated With High Blood Pressure Among Adolescents in India

High blood pressure (BP) in children and adolescents is becoming one of the most common health conditions worldwide and is much more widely prevalent than previously thought. To estimate the prevalence of high BP in adolescents in India and identify associated factors. This cross-sectional study is a secondary analysis of data from the Comprehensive National Nutrition Survey (CNNS, 2016-2018), which used a multistage, stratified, probability proportion to size cluster sampling design to enroll a nationally representative sample of households and individuals aged 10 to 19 years across all states and union territories of India. Adolescents with acute or chronic illness, physical deformity, mental illness, or cognitive disability were excluded from the survey. Because BP was measured only in children between 10 and 19 years of age, only data from children within this age group were included for secondary analyses. Data analysis was performed from March 2021 to April 2022. Anthropometry. On the basis of the 2017 American Academy of Pediatrics guidelines, high BP was defined as stage 1 and 2 hypertension, with BP above the 95th percentile in children younger than 13 years and greater than 130/80 mm Hg in children 13 years or older. The association of age, sex, region, socioeconomic status, body mass index, fasting blood glucose, hemoglobin A1c, and lipid profile with high BP were examined using log binomial regression. Among 16 182 eligible children aged 10 to 19 years (mean [SD] age, 14.2 [2.8] years; 7849 [48.5%] female and 8333 [51.5%] male), 11 718 had valid BP data with 3 repeated readings. the prevalence of high BP was 35.1% (95% CI, 31.5%-38.9%) in children aged 10 to 12 years and 25.1% (95% CI, 22.5%-28.0%) in children 13 years or older. Overweight and obesity were associated with a higher risk of high BP in both younger (prevalence ratio, 1.17; 95% CI, 1.04-1.34) and older children (prevalence ratio, 1.33; 95% CI, 1.18-1.49). The prevalence of high BP in younger children with stunting was high at 40.1% (95% CI, 31.9%-48.9%) and was 21.9% (95% CI, 18.2%-26.1%) among older children with stunting. In both age groups, high BP coexisted with other cardiovascular disease risk factors, such that adolescents with high fasting blood glucose, high hemoglobin A1c, high triglyceride, and high low-density lipoprotein cholesterol levels had a higher risk of high BP. In this cross-sectional study, the prevalence of high BP, along with cardiovascular risk factors, was substantial in Indian adolescents. There is a need to screen and identify adolescents who have high BP and initiate interventions to control the burden of hypertension and its consequences in India.

The prevalence, incidence and mortality associated with intra-abdominal hypertension among patients in intensive care units of a low-income country: a cohort study

Background: Intra-abdominal hypertension (IAH) is sustained increase in intra-abdominal pressure (IAP) ≥12 mmHg in adults and ≥10 mmHg in children. IAH has been noted to be associated with increased morbidity and mortality among critically ill patients. Measurement of IAP is common among at risk patients in the developed world. However, it has not received due attention in the majority of intensive care units (ICUs) in low-income countries, Uganda being one of these. This is evidenced by paucity of data and lack of protocols from the Ugandan Ministry of Health. This multi-center study was thus conducted to assess the prevalence, incidence and mortality associated with IAH among patients admitted to Ugandan ICUs.Methods:A multi-center prospective cohort study was conducted from September 2017 to February 2018 at three ICUs in Uganda. We consecutively enrolled 126 patients into the study. IAP was measured using the Harrahil manometer technique. Categorical variables were analyzed using the Chi square test and continuous variables analyzed using the t-test and Man Whitney test. The prevalence and incidence were determined using proportions and mortality was determined using survival analysis.Results:The median age was 33 years (26-48.5) for the patients without IAH and 42 years (29-55) for those with IAH. The majority of the patients were male and 9.6% of the patients were below 18 years. The prevalence of IAH was 62.7 (CI 54.1-71.3), whereas the 24 hour and 72 hour incidence of IAH was 9.3% (CI 1.3-17.2) and 14.3 % (CI 4.1-24.4), respectively. Mortality was higher in patients with IAH compared to those without (p-value 0.003 and 0.028, mean and maximum IAP, respectively). Conclusion:We found a high prevalence and incidence of IAH among critically ill patients, associated with a high mortality. Routine screening for IAH can preempt management strategies to mitigate this.

Negative Pressure Wound Therapy in Pediatric Burn Patients: A Systematic Review.

Significance: Negative pressure wound therapy (NPWT) requires the placement of a dressing over a wound, covered with an adhesive film, and applying to these dressing a negative pressure in a controlled fashion. This therapy is a powerful complement to surgical care of wounds. Data are however poor on its use in pediatric burns. Recent Advances: This systematic review, including a total of 466 patients, shows that NPWT as the initial treatment for burned children and after skin grafting has been shown to produce promising results. In the majority of studies, skin graft take rate is close to 100%. This therapy is particularly beneficial in the pediatric population because of less frequent dressing changes and early mobilization. NPWT devices accurately quantify burns water losses and allow tailoring liquid resuscitation. Critical Issues: NPWT is not in the subject of controlled clinical trials in pediatric; most publications are case reports or retrospective reviews. The sporadic complications include bleeding, local infections, and mechanical device issues. Future Directions: NPWT has been used in 2-month up to 18-year-old children with deep second- to third-degree burn of multiple etiologies, from a few days up to several months, on small to 40% total body surface area (%), and in difficult areas. Data gathered provide empirical guidelines on NPWT use in pediatric burns using continuous mode with a pressure of -50 to -75 mmHg for children younger than 2 years, and -75 to -125 mmHg in children over 2 years of age. Prospective randomized studies are needed to provide validated rules.

Use of Static Cutoffs of Hypertension to Determine High cIMT in Children and Adolescents: An International Collaboration Study

BackgroundPediatric hypertension is typically defined as blood pressure ≥ sex-, age-, and height-specific 95th percentile (high) cutoffs. Given the number of strata, there are hundreds of cutoffs for defining elevated and high blood pressure that make it cumbersome to use in clinical practice. This study aimed to evaluate the utility of the static cutoffs for pediatric hypertension (120/80 mm Hg for children and 130/80 mm Hg for adolescents) in determining high carotid intimamedia thickness (cIMT) in children and adolescents. MethodsData were from 6 population-based cross-sectional studies in Brazil, China, Greece, Italy, Spain, and the United Kingdom. A total of 4280 children and adolescents, aged 6 to 17 years, were included. High cIMT was defined as cIMT ≥ sex-, age- and cohort-specific 90th percentile cutoffs. ResultsCompared with normal blood pressure, hypertension defined using the percentile-based cutoffs from 2017 American Academy of Pediatrics guideline, and the static cutoffs were associated with similar higher odds for high cIMT (percentile-based cutoffs: odds ratio [OR], 1.46, 95% confidence interval [CI], 1.15-1.86; static cutoffs: OR, 1.65, 95% CI, 1.25-2.17), after adjustment for sex, age, race/ethnicity, body mass index, high-density lipoprotein-cholesterol, triglyceride, and fasting blood glucose. The similar utility of 2 definitions in determining high cIMT was further confirmed by area under the receiver operating characteristic curve and net reclassification improvement methods (P for difference > 0.05). ConclusionStatic cutoffs (120/80 mm Hg for children, 130/80 mm Hg for adolescents) performed similarly compared with percentile-based cutoffs in determining high cIMT, supporting the use of static cutoffs in identifying pediatric hypertension in clinical practice.

Venous-arterial CO2 difference in children with sepsis and its correlation with myocardial dysfunction.

Objective: This study aimed to determine the association between venous–arterial CO2 difference (Pv-aCO2) and clinical outcomes of interest in children with severe sepsis and septic shock. Design: An analytical observational study of a prospective cohort was conducted. Setting: The study was carried out from January 2015 to January 2018 in the pediatric intensive care unit of a referral hospital. Materials and methods: Of a total of 1159 patients who were admitted to pediatric critical care, 375 had severe sepsis and septic shock, of which 67 fulfilled the inclusion criteria. Arterial and venous gases were drawn simultaneously with a transthoracic echocardiogram, Pv-aCO2, and other measures of tissue perfusion such as arterial lactate, venous, and evolution to multiple organ failure. Measurements and main results: Half (53.7%) of the patients were under 24 months old, with a slight predominance of male patients. The main site of infection was the lungs in 56% of the cases, with a 91.2% survival rate. Patients who died had a higher venous lactate level (interquartile range 16.2–33.6, p = 0.02). However, there was no correlation between myocardial dysfunction seen on echocardiogram and a Pv-aCO2 greater than 6 mm Hg in children with severe sepsis and septic shock (r = 0.13). Pv-aCO2 and central venous saturation had low sensitivity to detect multiple organ failure and poor correlation with the number of compromised systems (r = 0.8). Conclusion: Pv-aCO2 was not associated with myocardial dysfunction, measured by echocardiogram, in children with severe sepsis and septic shock. It also did not correlate with the number of organs involved or mortality.

Survival and Cardiopulmonary Resuscitation Hemodynamics Following Cardiac Arrest in Children With Surgical Compared to Medical Heart Disease.

To assess the association of diastolic blood pressure cutoffs (≥ 25 mm Hg in infants and ≥ 30 mm Hg in children) during cardiopulmonary resuscitation with return of spontaneous circulation and survival in surgical cardiac versus medical cardiac patients. Secondarily, we assessed whether these diastolic blood pressure targets were feasible to achieve and associated with outcome in physiology unique to congenital heart disease (single ventricle infants, open chest), and influenced outcomes when extracorporeal cardiopulmonary resuscitation was deployed. Multicenter, prospective, observational cohort analysis. Tertiary PICU and cardiac ICUs within the Collaborative Pediatric Critical Care Research Network. Patients with invasive arterial catheters during cardiopulmonary resuscitation and surgical cardiac or medical cardiac illness category. None. Hemodynamic waveforms during cardiopulmonary resuscitation were analyzed on 113 patients, 88 surgical cardiac and 25 medical cardiac. A similar percent of surgical cardiac (51/88; 58%) and medical cardiac (17/25; 68%) patients reached the diastolic blood pressure targets (p = 0.488). Achievement of diastolic blood pressure target was associated with improved survival to hospital discharge in surgical cardiac patients (p = 0.018), but not medical cardiac patients (p = 0.359). Fifty-three percent (16/30) of patients with single ventricles attained the target diastolic blood pressure. In patients with an open chest at the start of chest compressions, 11 of 20 (55%) attained the target diastolic blood pressure. In the 33 extracorporeal cardiopulmonary resuscitation patients, 16 patients (48%) met the diastolic blood pressure target with no difference between survivors and nonsurvivors (p = 0.296). During resuscitation in an ICU, with invasive monitoring in place, diastolic blood pressure targets of greater than or equal to 25 mm Hg in infants and greater than or equal to 30 mm Hg in children can be achieved in patients with both surgical and medical heart disease. Achievement of diastolic blood pressure target was associated with improved survival to hospital discharge in surgical cardiac patients, but not medical cardiac patients. Diastolic blood pressure targets were feasible to achieve in 1) single ventricle patients, 2) open chest physiology, and 3) extracorporeal cardiopulmonary resuscitation patients.

Static cut‐points of hypertension and increased arterial stiffness in children and adolescents: The International Childhood Vascular Function Evaluation Consortium

Pediatric elevated blood pressure (BP) and hypertension are usually defined using traditional BP tables at the 90th and 95th percentiles, respectively, based on sex, age, and height, which are cumbersome to use in clinical practice. The authors aimed to assess the performance of the static cut-points (120/80mmHg and 130/80mmHg for defining elevated BP and hypertension for adolescents, respectively; and 110/70mmHg and 120/80mmHg for children, respectively) in predicting increased arterial stiffness. Using data from five population-based cross-sectional studies conducted in Brazil, China, Korea, and New Zealand, a total of 2546 children and adolescents aged 6-17years were included. Increased arterial stiffness was defined as pulse wave velocity ≥sex-specific, age-specific, and study population-specific 90th percentile. Compared to youth with normal BP, those with hypertension defined using the 2017 American Academy of Pediatrics guideline (hereafter referred to as "percentile-based cut-points") and the static cut-points were at similar risk of increased arterial stiffness, with odds ratios and 95% confidence intervals of 2.35 (1.74-3.17) and 3.07 (2.20-4.28), respectively. Area under the receiver operating characteristic curve and net reclassification improvement methods confirmed the similar performance of static cut-points and percentile-based cut-points (P for difference>.05). In conclusion, the static cut-points performed similarly well when compared with the percentile-based cut-points in predicting childhood increased arterial stiffness. Use of static cut-points to define hypertension in childhood might simplify identification of children with abnormal BP in clinical practice.

Is the Measurement of Blood Pressure by Automatic Monitor in the South American Pediatric Population Accurate? SAYCARE Study.

This study aimed to test the validity of an automatic oscillometric device to measure the blood pressure (BP) in children (n = 191) and adolescents (n = 127) aged 3 to 18 years. Systolic BP (SBP) and diastolic BP (DBP) levels were measured simultaneous by automatic device and mercury column with Y-connection. To verify the validity, Bland-Altman plots and limits of agreement of 95% (95% LOA), specificity and sensitivity of the device, and the grade of British Hypertension Society (BHS) criteria were used. The monitor measurements demonstrated lower measurement bias (mean difference [95% LOA]): 1.4 (-9.9 to 12.8) mmHg in children and 4.3 (-7.8 to 16.5) mmHg in adolescents for SBP. For DBP, it was 2.2 (-7.4 to 11.7) mmHg in children and 1.4 (-8.4 to 11.1) mmHg in adolescents. The sensitivity in children was 21.4 (95% CI = 16.3-26.6), and in adolescents, it was 20.0 (95% CI = 13.2-26.8); the specificity was 95.9 (95% CI = 93.4-98.4) in children and 100.0 (95% CI = 100.0-100.0) in adolescents. The monitor-tested ratings are Grade B for SBP in children and SBP and DBP in adolescents and Grade C for DBP in children. The automatic monitor presented high values of specificity and lower values of sensitivity to the diagnosis of HBP; however, it can be considered accurate (lower measurement bias) and valid for epidemiological and clinical practice in accordance with BHS criteria.

Association Between Diastolic Blood Pressure During Pediatric In-Hospital Cardiopulmonary Resuscitation and Survival.

On the basis of laboratory cardiopulmonary resuscitation (CPR) investigations and limited adult data demonstrating that survival depends on attaining adequate arterial diastolic blood pressure (DBP) during CPR, the American Heart Association recommends using blood pressure to guide pediatric CPR. However, evidence-based blood pressure targets during pediatric CPR remain an important knowledge gap for CPR guidelines. All children ≥37 weeks' gestation and <19 years old in Collaborative Pediatric Critical Care Research Network intensive care units with chest compressions for ≥1 minute and invasive arterial blood pressure monitoring before and during CPR between July 1, 2013, and June 31, 2016, were included. Mean DBP during CPR and Utstein-style standardized cardiac arrest data were collected. The hypothesis was that DBP ≥25 mm Hg during CPR in infants and ≥30 mm Hg in children ≥1 year old would be associated with survival. Primary outcome was survival to hospital discharge. Secondary outcome was survival to hospital discharge with favorable neurological outcome, defined as Pediatric Cerebral Performance Categories 1 to 3 or no worse than prearrest baseline. Multivariable Poisson regression models with robust error estimates were used to estimate the relative risk of outcomes. Blinded investigators analyzed blood pressure waveforms during CPR from 164 children, including 60% <1 year old, 60% with congenital heart disease, and 54% after cardiac surgery. The immediate cause of arrest was hypotension in 67%, respiratory decompensation in 44%, and arrhythmia in 19%. Median duration of CPR was 8 minutes (quartiles, 3 and 27 minutes). Ninety percent survived the event, 68% with return of spontaneous circulation and 22% by extracorporeal life support. Forty-seven percent survived to hospital discharge, and 43% survived to discharge with favorable neurological outcome. Maintaining mean DBP ≥25 mm Hg in infants and ≥30 mm Hg in children ≥1 year old occurred in 101 of 164 children (62%) and was associated with survival (adjusted relative risk, 1.7; 95% confidence interval, 1.2-2.6; P=0.007) and survival with favorable neurological outcome (adjusted relative risk, 1.6; 95% confidence interval, 1.1-2.5; P=0.02). These data demonstrate that mean DBP ≥25 mm Hg during CPR in infants and ≥30 mm Hg in children ≥1 year old was associated with greater likelihood of survival to hospital discharge and survival with favorable neurological outcome.

Liver and systemic hemodynamics in children with cirrhosis: Impact on the surgical management in pediatric living donor liver transplantation.

Cirrhosis in adults is associated with modifications of systemic and liver hemodynamics, whereas little is known about the pediatric population. The aim of this work was to investigate whether alterations of hepatic and systemic hemodynamics were correlated with cirrhosis severity in children. The impact of hemodynamic findings on surgical management in pediatric living donor liver transplantation (LT) was evaluated. Liver and systemic hemodynamics were studied prospectively in 52 children (median age, 1 year; 33 with biliary atresia [BA]). The hemodynamics of native liver were studied preoperatively by Doppler ultrasound and intraoperatively using invasive flowmetry. Portosystemic gradient was invasively measured. Systemic hemodynamics were studied preoperatively by Doppler transthoracic echocardiography and intraoperatively by using transpulmonary thermodilution. Hemodynamic parameters were correlated with Pediatric End-Stage Liver Disease (PELD) score and the histological degree of fibrosis (collagen proportionate area [CPA]). Cirrhosis was associated with a 60% reduction of pretransplant total liver flow (n = 46; median, 36 mL/minute/100 g of liver) compared with noncirrhotic livers (n = 6; median, 86 mL/minute/100 g; P = 0.002). Total blood flow into the native liver was negatively correlated with PELD (P < 0.001) and liver CPA (P = 0.005). Median portosystemic gradient was 14.5 mm Hg in children with cirrhosis and positively correlated with PELD (P < 0.001). Portal vein (PV) hypoplasia was observed mainly in children with BA (P = 0.02). Systemic hemodynamics were not altered in our children with cirrhosis. Twenty-one children met the intraoperative criteria for PV reconstruction using a portoplasty technique during the LT procedure and had a smaller PV diameter at pretransplant Doppler ultrasound (median = 3.4 mm; P < 0.001). Cirrhosis in children appears also as a hemodynamic disease of the liver, correlated with cirrhosis severity. Surgical technique for PV reconstruction during LT was adapted accordingly.

Lower systolic blood pressure at age 7 y in low-birth-weight children who received iron supplements in infancy: results from a randomized controlled trial

Background: Low birth weight (LBW) (≤2500 g) is associated with iron deficiency in infancy and high blood pressure (BP) later in life.Objective: We investigated the effect of iron supplementation that was given to LBW infants on midchildhood BP.Design: The study was a randomized, double-blind, controlled trial that included 285 marginally LBW (2000-2500-g) infants at 2 Swedish centers between May 2004 and November 2007. The infants were randomly assigned to receive a placebo or 1 or 2 mg Fe · kg-1 · d-1 from 6 wk to 6 mo of age. In secondary analyses at the age of 7 y, systolic blood pressure (SBP), diastolic blood pressure (DBP), and the prevalence of children with BP within the hypertensive range (>90th percentile) were compared between the groups.Results: BP was analyzed via intention to treat in 189 children (66%). The mean ± SD SBP was 103 ± 8.1, 101 ± 7.5, and 101 ± 7.8 mm Hg in children who had received the placebo (n = 70), 1 mg Fe · kg-1 · d-1 (n = 54), or 2 mg Fe · kg-1 · d-1 (n = 65), respectively. When the iron-supplemented groups were combined in covariate-adjusted analyses, the mean SBP in LBW children who had received iron supplementation in infancy was 2.2 mm Hg (95% CI: 0.3, 4.2 mm Hg) lower than in those who were unsupplemented (P = 0.026). Multivariate logistic regression showed that iron supplementation in infancy reduced the odds of having an SBP within the hypertensive range at 7 y of age (OR: 0.32; 95% CI: 0.11, 0.96). For DBP, there were no significant differences between the intervention groups.Conclusions: LBW children who receive iron supplementation (1 or 2 mg Fe · kg-1 · d-1) in infancy have lower SBP at 7 y. This (to our knowledge) novel observation suggests that the increased risk of hypertension that is observed in children and adults who are born small might be reduced with early micronutrient interventions. This trial was registered at clinicaltrials.gov as NCT00558454.

Can Pediatric Hypertension Criteria Be Simplified? A Prediction Analysis of Subclinical Cardiovascular Outcomes From the Bogalusa Heart Study.

Prehypertension and hypertension in childhood are defined by sex-, age-, and height-specific 90th (or ≥120/80 mm Hg) and 95th percentiles of blood pressure, respectively, by the 2004 Fourth Report. However, these cutoffs are complex and cumbersome for use. This study assessed the performance of a simplified blood pressure definition to predict adult hypertension and subclinical cardiovascular disease. The cohort consisted of 1225 adults (530 men; aged 26.3-47.7 years) from the Bogalusa Heart Study with 27.1-year follow-up since childhood. We used 110/70 and 120/80 mm Hg for children (age, 6-11 years), and 120/80 and 130/85 mm Hg for adolescents (age, 12-17 years) as the simplified definition of childhood prehypertension and hypertension, respectively, to compare with the 2004 Fourth Report (the complex definition). Adult carotid intima-media thickness, pulse wave velocity, and left ventricular mass were measured using digital ultrasound instruments. Compared with normal blood pressure, childhood hypertensives diagnosed by the simplified definition and the complex definition were both at higher risk of adult hypertension with hazard ratio of 3.1 (95% confidence interval, 1.8-5.3) by the simplified definition and 3.2 (2.0-5.0) by the complex definition, high pulse wave velocity with 3.5 (1.7-7.1) and 2.2 (1.2-4.1), high carotid intima-media thickness with 3.1 (1.7-5.6) and 2.0 (1.2-3.6), and left ventricular hypertrophy with 3.4 (1.7-6.8) and 3.0 (1.6-5.6). The results were confirmed by reclassification or receiver operating curve analyses. The simplified childhood blood pressure definition predicts the risk of adult hypertension and subclinical cardiovascular disease equally as the complex definition does, which could be useful for screening hypertensive children to reduce risk of adult cardiovascular disease.

The associated pneumoperitoneum increases intra-abdominal pressure (IAP), decreases systemic cardiac output and diminishes renal blood flow. This hypoperfusion may result in transient renal injury. The purpose of this study was to assess the short-term impact of pneumoperitoneum on renal function in children using sequential creatinine and cystatin C assays. METHODS Prospective analysis of all children over 12 months old who underwent laparoscopic or robotic surgery at a single institution between 9/2014 and 7/2015. For each patient, blood samples were obtained in the OR immediately prior to surgery, upon transfer to the recovery room, and on the morning of POD 1 if the child stayed overnight. Intraoperative parameters, including anesthesia time (a subset of total surgical time), were recorded. The IAP was maintained at 8 mmHg for children <10 years old and at 10 mmHg for older patients. Paired t tests and linear regression were performed for statistical analysis. RESULTS Over the 10-month study period, 20 children underwent laparoscopic (25%) or robotic (75%) surgery. 75% were boys. Patient and intraoperative characteristics are detailed in the table. The mean preoperative, immediate postoperative and POD 1 cystatin C values were 0.71 +/- 0.12, 0.65 +/- 0.10 and 0.60 +/- 0.12, respectively. Likewise, creatinine values were 0.35 +/-0.17, 0.41 +/- 0.18, and 0.36 +/- 0.17. There was no significant difference in cystatin C or creatinine values between the study time points. Linear regression analysis did not demonstrate an association between anesthesia time and postoperative creatinine or cystatin C values. CONCLUSIONS Pneumoperitoneum does not appear to affect renal function in children undergoing laparoscopic or robotic surgery. This study provides support for the use of low-pressure pneumoperitoneum and next generation valveless trocar systems. However, further investigation is warranted, given the limited sample size and relatively short duration of surgeries. © 2017FiguresReferencesRelatedDetails Volume 197Issue 4SApril 2017Page: e703 Advertisement Copyright & Permissions© 2017MetricsAuthor Information Julia Finkelstein More articles by this author Solomon Woldu More articles by this author Alexander Small More articles by this author Nina Mikkilineni More articles by this author Sarah Lambert More articles by this author Pasquale Casale More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
