at Fruit Consumption by Youth in the United States By pediatrics.aappublications.org Published On :: 2015-09-21T00:07:35-07:00 Although whole fruit intake has increased among US youth from 2003 to 2010, little is known about the specific types of fruits youth consume and whether consumption varies by age, poverty status, gender, and race or Hispanic origin.Twelve discrete fruits and fruit juices contribute almost 90% of total fruit consumed by US youth. Consumption of specific fruits and 100% fruit juices was associated with age and race or Hispanic origin but not gender or poverty status. (Read the full article) Full Article
at A Model for Predicting Significant Hyperbilirubinemia in Neonates From China By pediatrics.aappublications.org Published On :: 2015-09-21T00:07:35-07:00 Guidelines for postdischarge monitoring of hyperbilirubinemia for neonates of white descent are available from the American Academy of Pediatrics; however, such information for healthy term and late preterm Chinese neonates is lacking.A classification model for predicting the risk of significant hyperbilirubinemia in Chinese neonates was developed that combines a transcutaneous bilirubin–based nomogram with clinical risk factors. It classified newborns into 6 risk groups, which can guide clinicians in planning appropriate follow-up strategies. (Read the full article) Full Article
at Maternal Versus Infant Vitamin D Supplementation During Lactation: A Randomized Controlled Trial By pediatrics.aappublications.org Published On :: 2015-09-28T00:07:30-07:00 The vitamin D concentration in breast milk of women taking 400 IU vitamin D per day is relatively low, leading to vitamin D deficiency in breastfeeding infants. As a result, the American Academy of Pediatrics recommends breastfeeding infant vitamin D supplementation within days after birth.Maternal vitamin D supplementation alone with 6400 IU/day safely supplies breast milk with adequate vitamin D to satisfy the requirement of her nursing infant and offers an alternate strategy to direct infant supplementation.

at Intraurethral Lidocaine for Urethral Catheterization in Children: A Randomized Controlled Trial By pediatrics.aappublications.org Published On :: 2015-09-28T00:07:30-07:00 Urethral catheterization is a painful, yet common procedure to obtain a sterile urine sample in young children. There are conflicting results regarding the effectiveness of lidocaine to reduce pain, and it is unclear if it should be routinely used.In young children, combined topical and intraurethral lidocaine does not reduce pain during urethral catheterization and is associated with more pain than nonanesthetic lubricant during instillation. Clinicians should use noninvasive methods of analgesia during this painful procedure. (Read the full article) Full Article
at Preterm Infant Attendance at Health Supervision Visits By pediatrics.aappublications.org Published On :: 2015-09-28T00:07:29-07:00 Premature infants are at risk for medical and neurodevelopmental sequelae. Close monitoring is an important role for primary care providers. Premature infants have high use of health care services; however, little is known about the role of health supervision visits.This study explores the utilization and value of health supervision visits for premature infants. Fewer than half were found to be fully adherent to the health supervision visit schedule, resulting in preventive care gaps and immunization delays. (Read the full article) Full Article

at Point-of-Care Quantitative Measure of Glucose-6-Phosphate Dehydrogenase Enzyme Deficiency By pediatrics.aappublications.org Published On :: 2015-10-12T00:07:20-07:00 Glucose-6-phosphate dehydrogenase deficiency remains a global as well as a North American burden for extreme hyperbilirubinemia and kernicterus and is often unpredictable during the first few days after birth. Newborn screening for this enzyme deficiency is not universally available but debated.Point-of-care screening, using digital microfluidics, provides accurate, low blood volume, and affordable technology for rapid newborn glucose-6-phosphate dehydrogenase enzyme screening that could guide clinicians before infants’ discharge from well-child nurseries and meet existing American Academy of Pediatrics’ recommendations.

at Use of a Metronome in Cardiopulmonary Resuscitation: A Simulation Study By pediatrics.aappublications.org Published On :: 2015-10-12T00:07:20-07:00 The frequency of cardiac arrest is significantly lower in children than in adults, rendering the delivery of high-quality cardiopulmonary resuscitation more difficult. Metronome-based studies in adults showed improvement in adequate compression rate, with a detrimental effect on the depth of chest compressions.This is the first pediatric study to confirm that the use of a metronome during cardiopulmonary resuscitation significantly improves the delivery of adequate rate without affecting the compression depth. This effect was more prominent among medical students and pediatric residents and fellows than nurses. (Read the full article) Full Article

There are more pediatric outpatient mental health care visits to primary care physicians (PCPs) than to psychiatrists. Mental health utilization patterns regarding different conditions and medication prescribing are unknown.One-third of children with mental health conditions see PCPs only. A greater proportion of children with attention-deficit/hyperactivity disorder see PCPs for this than do those with anxiety/mood disorders.

at Early-Onset Neutropenia in Small-for-Gestational-Age Infants By pediatrics.aappublications.org Published On :: 2015-10-12T00:07:19-07:00 Small for gestational age neonates (weight <10th percentile) are at risk for neutropenia during the first days after birth. However, the duration, responsible mechanism, and outcomes of this variety of neonatal neutropenia are not precisely known.Six percent of small for gestational age neonates had neutrophils <1000/μL, with an average neutropenia duration of 7 days. Neutropenia was more closely linked with small for gestational age status than maternal hypertension. This neutropenia is associated with elevated nucleated red blood cell count and increased odds of necrotizing enterocolitis. (Read the full article) Full Article

at Racial and Regional Differences in Rates of Invasive Pneumococcal Disease By pediatrics.aappublications.org Published On :: 2015-10-12T00:07:19-07:00 Previous studies have shown racial differences in invasive pneumococcal disease (IPD) rates. Recent studies demonstrated a national decline in IPD rates after 13-valent pneumococcal conjugate vaccine (PCV13) introduction. The impact of PCV13 on racial and regional differences in IPD rates among Tennessee children is unknown.After introduction of PCV13, pediatric IPD rates, including disease due to antibiotic-resistant strains, declined substantially. Racial and regional differences in IPD rates were no longer significant. Our study illustrates the impact of PCV13 and the importance of continued IPD surveillance.

at ‘He was larger than life’: Brooklyn mourns death of Grand Prospect Hall owner Michael Halkias By feedproxy.google.com Published On :: Sat, 09 May 2020 14:01:00 GMT Source: www.brooklynpaper.com - Saturday, May 09, 2020 The owner of the iconic Park Slope events venue Grand Prospect Hall, Michael Halkias, died from COVID-19 on Wednesday. He was 82. Halkias’ death sent shockwaves throughout Brooklyn, where community leaders and friends remember him as a passionate, generous figure. “ He was a Brooklyn character for sure in the best sort of way,” said Randy Peers, president and CEO of the Brooklyn Chamber of Commerce. “He was larger than life.” Halkias and his wife Alice bought Grand Prospect Hall in 1984 and turned the extravagant Prospect Avenue building into an opulent catering hall. The space became a New York icon because of the its long-running, popular commercials, where Alice Halkias declares in a Greek accent, “We make your dreams come true!” Saturday Night Live spoofed the famous commercial in February of 2019, and the pair appeared on Jimmy Kimmel Live in October to remake the ad with Mets player Pete Alonso. Grand Prospect Hall, a Victorian banquet hall built in 1892, attracted big names such as dancer Fred Astaire and mafioso Al Capone during its heyday in the early 20th century — and boasted some of the borough’s oldest treasures, such as Brooklyn’s first reported elevator, which functions to this day. But by the 1980s, the landmarked building had fallen into disrepair: its walls had been painted black, molding had been stripped off the walls, and the chandeliers were gone, Halkias told Brooklyn Paper in 2004.
