Managing Diagnostic Uncertainty in Pediatric Sepsis Quality Improvement with a Two-Tiered Approach.

Severe sepsis requires timely, resource-intensive resuscitation, a challenge when a sepsis diagnosis is not confirmed. The overall goals were to create a pediatric sepsis program that provided high-quality critical care in severe sepsis (Sepsis Stat), and, in possible sepsis, flexible evaluation and treatment that promoted stewardship (Sepsis Yellow). The primary aims were to decrease time to antibiotics and the intensive care unit requirement. METHODS: A 2-tiered clinical pathway was implemented at 6 pediatric emergency departments and urgent care centers, incorporating order sets, education, paging. The Sepsis Stat pathway included 2 nurses, hand delivery of antibiotics, resuscitation room use. The Sepsis Yellow pathway included prioritized orders, standardized procedures, close monitoring, and evaluation of whether antibiotics were warranted. RESULTS: From April 2012 to December 2017, we treated 3,640 patients with suspected and confirmed sepsis. Among the 932 severe sepsis patients, the 30-day, in-hospital mortality was 0.9%. Arrival to recognition time improved from 50 to 4 minutes. Recognition to antibiotic time demonstrated an in-control process in our goal range with a median of 43 minutes for Sepsis Stat patients, 59 minutes for Sepsis Yellow patients. The proportion of severe sepsis patients requiring intensive care unit care declined from 45% to 34%. On the Sepsis Yellow pathway, 23% were de-escalated with discharge to home without antibiotics. CONCLUSIONS: This novel 2-tiered approach to pediatric sepsis quality improvement in varied emergency care settings improved process and outcome measures in severe sepsis while promoting stewardship and de-escalation where appropriate. Matching resources to the degree of illness was important in supporting quality care in potentially septic children.

Protein-source tryptophan as an efficacious treatment for social anxiety disorder: a pilot study.

Until recently, intact protein that is rich in tryptophan was not seen as an alternative to pharmaceutical-grade tryptophan because protein also contains large neutral amino acids (LNAAs) that compete for transport sites across the blood-brain barrier. Recent evidence indicates that when deoiled gourd seed (a rich source of tryptophan with approximately 22 mg/g protein) is combined with glucose (a carbohydrate that reduces serum levels of competing LNAAs) a clinical effect similar to that of pharmaceutical-grade tryptophan is achieved. Objective and subjective measures of anxiety in those suffering from social phobia (also known as social anxiety disorder) were employed to measure changes in anxiety in response to a stimulus as part of a double-blind, placebo-controlled, crossover study with a wash-out period of 1 week between study sessions. Subjects were randomly assigned to start with either (i) protein-source tryptophan (deoiled gourd seed) in combination with carbohydrate or (ii) carbohydrate alone. One week after the initial session, subjects returned for a follow-up session and received the opposite treatment of that received at the first session. All 7 subjects who began the study completed the 2-week protocol. Protein-source tryptophan with carbohydrate, but not carbohydrate alone, resulted in significant improvement on an objective measure of anxiety. Protein-source tryptophan combined with a high glycemic carbohydrate is a potential anxiolytic to those suffering from social phobia.

A Scottish study of heel-prick blood sampling in newborn babies.

OBJECTIVE: to conduct a randomised-controlled trial to investigate the effectiveness of two heel-prick devices (Tenderfoot and Genie Lancet) used in the newborn-baby screening test. DESIGN: a randomised-controlled trial. PARTICIPANTS AND SETTING: the homes of 340 healthy term newborn babies discharged from the maternity unit of Stirling Royal Infirmary, Scotland. Data were collected between April and November 2003. INTERVENTIONS: babies were randomly allocated to be tested with either the Tenderfoot or Genie Lancet heel-prick device. MEASUREMENTS: primary study outcomes include (1) quality of the blood sample; (2) time taken to collect the sample; (3) number of heel pricks required to take the sample; (4) whether squeezing of heel was required; (5) pain expressed by the baby; and (6) presence of bruising. A potential intervening variable was the experience of the midwife. FINDINGS: on all outcomes, the Tenderfoot device was more effective than the Genie Lancet. Experienced midwives were more efficient in sample collection. KEY CONCLUSIONS: this study shows that the Tenderfoot device saves significant time for midwifery staff, improves baby care and reduces the need for more than one heel prick at each test, making it superior to the Genie Lancet device. IMPLICATIONS FOR PRACTICE: there is a case to be made for midwives to be issued with the Tenderfoot device for neonatal screening.

Pediatric diabetic ketoacidosis: clinical presentations and nursing considerations.

Pediatric diabetic ketoacidosis is a life-threatening medical condition that requires rapid recognition yet gradual organized treatment. This article discusses the pathophysiology and morbidity of diabetic ketoacidosis and cerebral edema, in addition to treatment and nursing considerations. Three case studies are presented to reintroduce the reader to varying severity of ketoacidosis.

Protein source tryptophan versus pharmaceutical grade tryptophan as an efficacious treatment for chronic insomnia.

BACKGROUND: Intact protein rich in tryptophan was not seen as an alternative to pharmaceutical grade tryptophan since protein also contains large neutral amino acids (LNAAs) that compete for transport sites across the blood-brain barrier (BBB). Deoiled gourd seed (an extremely rich source of tryptophan-22 mg tryptophan/1 g protein) was combined with glucose, a carbohydrate that reduces serum levels of competing LNAAs which was then compared to pharmaceutical grade tryptophan with carbohydrate as well as carbohydrate alone. METHOD: Objective and subjective measures of sleep were employed to measure changes in sleep as part of a double blind placebo controlled study where subjects were randomly assigned to one of three conditions: (1) Protein source tryptophan (deoiled gourd seed) in combination with carbohydrate; (2) pharmaceutical grade tryptophan in combination with carbohydrate; (3) carbohydrate alone. SUBJECTS: Out of 57 subjects 49 of those who began the study completed the three week protocol. RESULTS: Protein source tryptophan with carbohydrate and pharmaceutical grade tryptophan, but not carbohydrate alone, resulted in significant improvement on subjective and objective measures of insomnia. Protein source tryptophan with carbohydrate alone proved effective in significantly reducing time awake during the night. CONCLUSION: Protein source tryptophan is comparable to pharmaceutical grade tryptophan for the treatment of insomnia.
