A Simple and Prudent Proposal for Ending the Black Student Achievement Gap in Public Schools

Jonathan Kozol wants public schools in America to be accountable to students. He advocates an end to the corporate model of education currently being practiced in school districts across the country and asks that we no longer allow schools to frame their students’ realities by transmitting the values and beliefs of the powerful elite (Kozol, 2005). After four decades of critically examining and witnessing about the structure and operations of our modern-day educational system that descended from the decision rendered in Brown v. Board of Education 10 years prior, he asks that our nation begin to pay up on its promise to provide an educational experience in which black students learn because of and not in spite of their attendance in school

Rethinking Placental Transfusion and Cord Clamping Issues

A brief delay in clamping the umbilical cord results in a placental transfusion that supplies the infant with a major source of iron during the first few months of life. Cord circulation continues for several minutes after birth and placental transfusion results in approximately 30% more blood volume. Gravity influences the amount of placental transfusion that an infant receives. Placing the infant skin-to-skin requires a longer delay of cord clamping (DCC) than current recommendations. Uterotonics are not contraindicated with DCC. Cord milking is a safe alternative to DCC when one must cut the cord prematurely. Recent randomized controlled trials demonstrate benefits for term and preterm infants from DCC. The belief that DCC causes hyperbilirubinemia or symptomatic polycythemia is unsupported by the available research. Delay of cord clamping substantively increases iron stores in early infancy. Inadequate iron stores in infancy may have an irreversible impact on the developing brain despite oral iron supplementation. Iron deficiency in infancy can lead to neurologic issues in older children including poor school performance, decreased cognitive abilities, and behavioral problems. The management of the umbilical cord in complex situations is inconsistent between birth settings. A change in practice requires collaboration between all types of providers who attend births

Clinical Characteristics and Burden of Illness in Pediatric Patients with Narcolepsy

Abstract Background: Narcolepsy is a chronic and lifelong neurologic disorder with onset commonly occurring in childhood or adolescence, and affecting approximately 0.025% to 0.05% of the general population. The primary symptom is excessive daytime sleepiness, which is accompanied by cataplexy in 70% of patients. Other common symptoms include sleep paralysis, hallucinations upon falling asleep or waking, and disrupted nocturnal sleep. Narcolepsy is associated with a considerable burden of illness (BOI), which has been well characterized in adults, and is exacerbated by delays in symptom recognition, diagnosis, and intervention. METHODS: This review describes the specific characteristics and BOI of pediatric narcolepsy, using a wide range of published research data. RESULTS: Pediatric narcolepsy presents distinct challenges in diagnosis and management. Narcolepsy symptoms often initially manifest differently in children and adolescents versus adults, which may pose diagnostic dilemmas. Children often respond to sleepiness with irritability, hyperactivity, and poor attention, which may be misinterpreted as misbehavior or neurocognitive sequelae of other conditions. Pediatric cataplexy symptoms may include subtle and unusual facial expressions or choreic-like movements, which are not observed in adults. Insufficient sleep and circadian rhythm disorders presenting with excessive daytime sleepiness are common in adolescents, potentially confounding narcolepsy diagnosis. Pediatric narcolepsy is also associated with comorbidities including rapid weight gain, precocious puberty, and attention deficit hyperactivity disorder, and increased risk for deficits in social functioning, depression, and anxiety. School performance is also typically impaired, requiring special education services. CONCLUSIONS: Thus, the discrete BOI of pediatric narcolepsy underscores the need for prompt and accurate diagnosis, and appropriate treatment of this disorder

Cardiac asystole at birth: Is hypovolemic shock the cause?

A birth involving shoulder dystocia can rapidly deteriorate—from a fetus with a reassuring tracing in the minutes before birth, to a neonate needing aggressive resuscitation. Infants experiencing a traumatic birth involving shoulder dystocia may be severely compromised, even when the preceding labor was uncomplicated. This paper presents two cases in which infants had normal heart beats recorded 5–10 min before birth and were born with cardiac asystole following shoulder dystocia. Often, in cases of shoulder dystocia, infants shift blood to the placenta due to the tight compressive squeeze of the body in the birth canal (along with cord compression) and thereby may be born hypovolemic. Our hypothesis is that the occurrence of sudden cardiac asystole at birth is due to extreme hypovolemic shock secondary to the loss of blood. At birth, the sudden release of pressure on the infant’s body results in hypoperfusion resulting in low central circulation and blood pressure. Severe hypovolemic shock from these effects leads to sudden cardiac arrest. Immediate cord clamping maintains the hypovolemic state by preventing the physiologic and readily available placental blood from returning to the infant. Loss of this blood initiates an inflammatory response leading to seizures, hypoxic-ischemic encephalopathy, and brain damage or death. Animal studies have shown that human umbilical stem cells injected into a rat’s abdomen after induced brain damage, can protect the rat’s brain from developing permanent injury. To prevent damage to newborns, the infant must receive the blood volume and stem cells lost at the time of descent and immediate cord clamping. Recommended countermeasures for research include: (1) resuscitation at the perineum with intact cord; or (2) milking the cord before clamping; or (3) autologous transfusion of placenta blood after the birth; or (4) rapid transfusion of O negative blood after birth and before seizures begin

Facilitating Lewin\u27s change model with collaborative evaluation in promoting evidence based practices of health professionals

Evidence based practices (EBPs) in clinical settings interact with and adapt to host organizational characteristics. The contextual factors themselves, surrounding health professions’ practices, also adapt as practices become sustained. The authors assert the need for better planning models toward these contextual factors, the influence of which undergird a well-documented science to practice gap in literature on EBPs. The mechanism for EBP planners to anticipate contextual effects as programs Unfreeze their host settings, create Movement, and become Refrozen (Lewin, 1951) is present in Lewin\u27s 3-step change model. Planning for contextual change appears equally important as planning for the actual practice outcomes among providers and patients. Two case studies from a Geriatric Education Center network will illustrate the synthesis of Lewin\u27s three steps with collaborative evaluation principles. The use of the model may become an important tool for continuing education evaluators or organizations beginning a journey toward EBP demonstration projects in clinical settings

Effect of Experimental Change in Children’s Sleep Duration on Television Viewing and Physical Activity

Background Paediatric observational studies demonstrate associations between sleep, television viewing and potential changes in daytime activity levels. Objective(s) To determine whether experimental changes in sleep lead to changes in children's sedentary and physical activities. Methods Using a within-subject counterbalanced design, 37 children 8–11 years old completed a 3-week study. Children slept their typical amount during a baseline week and were then randomized to increase or decrease mean time in bed by 1.5 h/night for 1 week; the alternate schedule was completed the final week. Children wore actigraphs on their non-dominant wrist and completed 3-d physical activity recalls each week. Results Children reported watching more television (p < 0.001) and demonstrated lower daytime actigraph-measured activity counts per epoch (p = 0.03) when sleep was decreased (compared with increased). However, total actigraph-measured activity counts accrued throughout the entire waking period were higher when sleep was decreased (and children were awake for longer) than when it was increased (p < 0.001). Conclusion(s) Short sleep during childhood may lead to increased television viewing and decreased mean activity levels. Although additional time awake may help to counteract negative effects of short sleep, increases in reported sedentary activities could contribute to weight gain over time

Long-Term Outcomes After Surgical Versus Transcatheter Closure of Atrial Septal Defects in Adults

ObjectivesThe purpose of this study was to assess the comparative effectiveness and long-term safety of transcatheter versus surgical closure of secundum atrial septal defects (ASD) in adults.BackgroundTranscatheter ASD closure has largely replaced surgery in most industrialized countries, but long-term data comparing the 2 techniques are limited.MethodsWe performed a retrospective population-based cohort study of all patients, ages 18 to 75 years, who had surgical or transcatheter ASD closure in Québec, Canada's second-largest province, using provincial administrative databases. Primary outcomes were long-term (5-year) reintervention and all-cause mortality. Secondary outcomes were short-term (1-year) onset of congestive heart failure, stroke, or transient ischemic attack, and markers of health service use.ResultsOf the 718 ASD closures performed between 1988 and 2005, 383 were surgical and 335 were transcatheter. The long-term reintervention rate was higher in patients with transcatheter ASD closure (7.9% vs. 0.3% at 5 years, p = 0.0038), but the majority of these reinterventions occurred in the first year. Long-term mortality with the transcatheter technique was not inferior to surgical ASD closure (5.3% vs. 6.3% at 5 years, p = 1.00). Secondary outcomes were similar in the 2 groups.ConclusionsTranscatheter ASD closure is associated with a higher long-term reintervention rate and long-term mortality that is not inferior to surgery. Overall, these data support the current practice of using transcatheter ASD closure in the majority of eligible patients and support the decision to intervene on ASD with significant shunts before symptoms become evident

Making the Argument for Intact Cord Resuscitation: A Case Report and Discussion

We use a case of intact cord resuscitation to argue for the beneficial effects of an enhanced blood volume from placental transfusion for newborns needing resuscitation. We propose that intact cord resuscitation supports the process of physiologic neonatal transition, especially for many of those newborns appearing moribund. Transfer of the residual blood in the placenta provides the neonate with valuable access to otherwise lost blood volume while changing from placental respiration to breathing air. Our hypothesis is that the enhanced blood flow from placental transfusion initiates mechanical and chemical forces that directly, and indirectly through the vagus nerve, cause vasodilatation in the lung. Pulmonary vascular resistance is thereby reduced and facilitates the important increased entry of blood into the alveolar capillaries before breathing commences. In the presented case, enhanced perfusion to the brain by way of an intact cord likely led to regained consciousness, initiation of breathing, and return of tone and reflexes minutes after birth. Paramount to our hypothesis is the importance of keeping the umbilical cord circulation intact during the first several minutes of life to accommodate physiologic neonatal transition for all newborns and especially for those most compromised infants
