Rate of rise of total serum bilirubin in very low birth weight preterm infants.

BACKGROUND: To assess the postnatal rate of rise (ROR) of total serum bilirubin (TSB) in very low birth weight (VLBW) preterm infants, to determine risk factors associated with a rapid rise (>90th percentile), and to compare ROR and hour-specific TSB at postnatal 12-48 h with data of term infants retrieved from the literature. METHODS: Retrospective analysis of 2430 routine TSB concentrations obtained between birth and initiation of phototherapy in 483 VLBW infants. RESULTS: TSB increased by a median (interquartile range) ROR of 0.15 (0.11-0.19) mg/dL/h. The 50th percentile of TSB was below the 40th percentile of (near-)term counterparts at 12-48 h. TSB ROR correlated with the age at initiation (RS = -0.687; p < 0.001) and the duration (RS = 0.444; p < 0.001) of phototherapy. ROR >90th percentile (>0.25 mg/dL/h) was associated with lower gestational ages [27.2 (25.4-29.3) vs. 28.4 (26.4-30.4) weeks], lower birth weights [978 (665-1120) vs. 1045 (814-1300) g], and lower 5-min Apgar scores [7 (7-8) vs. 8 (7-9)]. CONCLUSION: ROR of TSB is an indicator for early and prolonged phototherapy. While hour-specific TSB and ROR at 12-48 h are lower than those reported for (near-)term infants, TSB appears to rise more rapidly in infants with low gestational age, low birth weight, and low 5-min Apgar score.

Open-Source Technology for Real-Time Continuous Glucose Monitoring in the Neonatal Intensive Care Unit: Case Study in a Neonate With Transient Congenital Hyperinsulinism.

BACKGROUND: Use of real-time continuous glucose monitoring (rtCGM) systems has been shown to be a low-pain, safe, and effective method of preventing hypoglycemia and hyperglycemia in people with diabetes of various age groups. Evidence on rtCGM use in infants and in patients with conditions other than diabetes remains limited. OBJECTIVE: This case study describes the off-label use of rtCGM and the use of an open-source app for glucose monitoring in a newborn with prolonged hypoglycemia secondary to transient congenital hyperinsulinism during the perinatal period. METHODS: The Dexcom G6 rtCGM system (Dexcom, Inc) was introduced at 39 hours of age. Capillary blood glucose checks were performed regularly. In order to benefit from customizable alert settings and detect hypoglycemic episodes, the open-source rtCGM app xDrip+ was introduced at 9 days of age. RESULTS: Time in range (45-180 mg/dL) for interstitial glucose remained consistently above 90%, whereas time in hypoglycemia (<45 mg/dL) decreased. Mean glucose was maintained above 70 mg/dL at 72 hours of life and thereafter. Daily sensor glucose profiles showed cyclic fluctuations that were less pronounced over time. CONCLUSIONS: While off-label use of medication is both common practice and a necessity in newborn infants, there are few examples of off-label uses of medical devices, rtCGM being a notable exception. Real-time information allowed us to better understand glycemic patterns and to improve the quality of glycemic control accordingly. Severe hypoglycemia was prevented, and measurement of serum levels of insulin and further lab diagnostics were performed much faster, while the patient's individual burden caused by invasive procedures was reduced. Greater customizability of threshold and alert settings would be beneficial for user groups with glycemic instability other than people with diabetes, and for hospitalized newborn infants in particular. Further research in the field of personal and off-label rtCGM use, efficacy studies evaluating the accuracy of low glucose readings, and studies on the differences between algorithms in translating raw sensor data, as well as customization of commercially available rtCGM systems, is needed.

Global health education in emergency medicine residency programs.

BACKGROUND: Interest in global health and international electives is growing among Emergency Medicine (EM) residents in the United States (US). The majority of EM residency programs offer opportunities for international electives. The degree of participation among residents and type of support provided by the residency program, however, remains unclear. STUDY OBJECTIVES: To explore the current state of global health education among EM residents who participate in international electives. METHODS: A 12-question survey was e-mailed to the program directors of the 192 EM residency programs in the US. The survey included questions about the number of residents participating in international electives and the types of preparation, project requirements, supervision, and feedback participating residents receive. RESULTS: The response rate was 53% with 102 responses. Seventy-five of 102 (74%) programs reported that at least one resident participated in an international elective in the 2010-2011 academic year. Forty-three programs (42%) report no available funding to support any resident on an international elective. Residents receive no preparation for international work in 41 programs (40%). Only 25 programs (26%) required their residents to conduct a project while abroad. Forty-nine programs (48%) reported no formal debriefing session, and no formal feedback was collected from returning residents in 57 of 102 (59%) programs. CONCLUSION: The majority of EM residencies have residents participating in international electives. However, the programs report variable preparation, requirements, and resident supervision. These results suggest a need for an expanded and more structured approach to international electives undertaken by EM residents.

Impact of mental health training on village health workers regarding clinical depression in rural India.

Village health worker (VHW) programs are known to be effective means of promoting health of communities. Comprehensive rural health project in India recently trained VHWs to identify, refer, and help people with mental health issues. This study evaluated knowledge, attitude, and behavior of VHWs regarding depression. Cluster sampling was used including all 36 VHWs trained in mental health. Among these, 24 were available and willing to participate in the study. Five FGDs were conducted among 24 VHWs, and the results were analyzed qualitatively. Four out of five groups were able to diagnose the presented case correctly as depression. VHWs were able to identify many symptoms and to suggest management options for depression. They showed supportive and empathetic attitudes towards depressed patients. VHWs are likely to be useful at identifying and assisting people with depression in the communities with lack of adequate resources provided they receive ongoing training and supervision.

Clinical policy: Critical issues in the initial evaluation and management of patients presenting to the emergency department in early pregnancy.

This clinical policy from the American College of Emergency Physicians is the revision of the 2003 Clinical Policy: Critical Issues in the Initial Evaluation and Management of Patients Presenting to the Emergency Department in Early Pregnancy.(1) A writing subcommittee reviewed the literature to derive evidence-based recommendations to help clinicians answer the following critical questions: (1) Should the emergency physician obtain a pelvic ultrasound in a clinically stable pregnant patient who presents to the emergency department (ED) with abdominal pain and/or vaginal bleeding and a beta human chorionic gonadotropin (ß-hCG) level below a discriminatory threshold? (2) In patients who have an indeterminate transvaginal ultrasound, what is the diagnostic utility of ß-hCG for predicting possible ectopic pregnancy? (3) In patients receiving methotrexate for confirmed or suspected ectopic pregnancy, what are the implications for ED management? Evidence was graded and recommendations were developed based on the strength of the available data in the medical literature. A literature search was also performed for a critical question from the 2003 clinical policy.(1) Is the administration of anti-D immunoglobulin indicated among Rh-negative women during the first trimester of pregnancy with threatened abortion, complete abortion, ectopic pregnancy, or minor abdominal trauma? Because no new, high-quality articles were found, the management recommendations from the previous policy are discussed in the introduction.

Diagnosis and management of ST elevation myocardial infarction: a review of the recent literature and practice guidelines.

There is a large volume of literature available to guide the peri-infarct management of ST elevation myocardial infarction (STEMI). Most of this literature focuses on improving the availability and efficacy of reperfusion therapy. The purpose of this article is to review contemporary scientific evidence and guideline recommendations regarding the diagnosis and therapy of STEMI. Studies and epidemiological data were identified using Medline, the Cochrane Database, and an Internet search engine. Medline was searched for landmark and recent publications using the following key words: STEMI, guidelines, epidemiology, reperfusion, fibrinolytics, percutaneous coronary intervention (PCI), facilitated PCI, transfer, delay, clopidogrel, glycoprotein IIb/IIIa, low-molecular-weight heparin (LMWH), beta-blockers, nitrates, and angiotensin-converting enzyme (ACE) inhibitors. The data accessed indicate that urgent reperfusion with either fibrinolytics or percutaneous intervention should be considered for every patient having symptoms of myocardial infarction with ST segment elevation or a bundle branch block. The utility of combined mechanical and pharmacological reperfusion is currently under investigation. Ancillary treatments may utilize clopidogrel, glycoprotein IIb/IIIa inhibitors, or low molecular weight heparin, depending on the primary reperfusion strategy used. Comprehensive clinical practice guidelines incorporate much of the available contemporary evidence, and are important resources for the evidence-based management of STEMI.

The evaluation and management of the acutely agitated elderly patient.

Delirium is an organic mental syndrome defined by a global disturbance in consciousness and cognition, which develops abruptly and often fluctuates over the course of the day. It is precipitated by medical illness, substance intoxication/withdrawal or medication effect. Delirium is associated with significant morbidity and mortality, and is a leading presenting symptom of illness in the elderly. Elderly patients with altered mental status, including agitation, should be presumed to have delirium until proven otherwise. The clinical manifestations of delirium are highly variable. A mental status evaluation is crucial in the diagnosis of delirium. Medical evaluation and stabilization should occur in parallel. Life-threatening etiologies including hypoxia, hypoglycemia and hypotension require immediate intervention. The differential diagnosis of etiologies of delirium is extensive. Patients with delirium need thorough evaluations to determine the underlying causes of the delirium. Pharmacological agents should be considered when agitated patient has the potential to harm themselves or others, or is impeding medical evaluation and management. Unfortunately, the evidence to guide pharmacologic management of acute agitation in the elderly is limited. Current pharmacologic options include the typical and atypical antipsychotic agents and the benzodiazepines. These therapeutic options are reviewed in detail.

Smaller cerebral aneurysms producing more extensive subarachnoid hemorrhage following rupture: a radiological investigation and discussion of theoretical determinants.

OBJECT: The goal of this study was to determine the relationship between aneurysm size and the volume of subarachnoid hemorrhage (SAH). METHODS: One hundred consecutive patients who presented with acute SAH, which was diagnosed on the basis of a computerized tomography (CT) scan within 24 hours postictus and, subsequently, confirmed to be aneurysmal in origin by catheter angiography, were included in this study. The data were collected prospectively in 32 patients and retrospectively in 68. The volume of SAH on the admission CT scan was scored in a semiquantitative manner from 0 to 30, according to a previously published method. The mean aneurysm size was 8.3 mm (range 1-25 mm). The mean SAH volume score was 15 (range 0-30). Regression analysis revealed that a smaller aneurysm size correlated with a more extensive SAH (r(2) = 0.23, p < 0.0001). Other variables including patient sex and age, intraparenchymal or intraventricular hemorrhage, multiple aneurysms, history of hypertension, and aneurysm location were not statistically associated with a larger volume of SAH. CONCLUSIONS: Smaller cerebral aneurysm size is associated with a larger volume of SAH. The pathophysiological basis for this correlation remains speculative.

Cross-sectional survey of malaria prevalence in tsunami-affected districts of Aceh Province, Indonesia.

BACKGROUND: Malaria is endemic to Indonesia. However, there are few prevalence data available from Aceh Province because of the long-standing separatist conflict and decentralization of the public health system. The Mentor Initiative, which specializes in malaria control in humanitarian emergencies, was one of the non-governmental organizations to respond to the 2004 Indian Ocean tsunami in Aceh. Data on malaria prevalence were gathered to guide and evaluate programmatic efforts. FINDINGS: The Mentor Initiative conducted community-based malaria prevalence surveys in 2005 and 2006 in five districts along the tsunami-affected western coastline. A total of 11,763 individuals in 3,771 households were tested. The overall slide positivity rate in 2005 and 2006 for all Plasmodium species was 2.1% (n = 252, 95% CI 1.9%-2.4%). Slide positivity rates ranged from 0 to 55% among villages. Overall, 57% of the 252 cases were infected with P. falciparum (n = 144, 95% CI 51.0%-63.3%), and 40.1% were infected with P. vivax (n = 101, 95% CI 34.0%-46.1%), with 0.03% (n = 7, 95% CI 0.8%-4.8%) being mixed infections. Males were significantly more likely to be affected than females (2.8% vs 1.5%, p < 0.01). Infection was more common in those over the age of 5 (2.3% vs. 0.6%, p < 0.01). CONCLUSIONS: Local prevalence data are needed to design effective community-based malaria control programs, as endemicity varies greatly within districts. Certain villages were found to be hyperendemic, with slide positivity rates far higher than average in Indonesia. There is a need for ongoing malaria surveillance in Aceh Province to monitor prevention and treatment efforts.
