BETHESDA, MD — President Obama joined other U.S. government and health leaders at a preparedness summit urging Americans to plan now for a likely surge in cases of the 2009-H1N1 influenza this fall.

"We want to make sure that we are not promoting panic, but we are promoting vigilance and preparation," President Obama, who was in Italy, said by phone during the summit on July 9 at the National Institutes of Health in Bethesda, Md.

"Our goals are straightforward; to reduce illness and death and minimize social disruption," said Dr. Thomas R. Frieden, director of the Centers for Disease Control and Prevention.

Dr. Frieden, along with Kathleen Sebelius, secretary of the Department of Health and Human Services, Janet Napolitano, secretary of the Department of Homeland Security, and Arne Duncan, secretary of the Department of Education, reviewed the status of the government's efforts to prepare for an anticipated surge in volume of cases of the 2009-H1N1 flu in the fall.

Secretary Sebelius summarized the government's four-pronged strategy of surveillance, community mitigation, vaccination, and communication. She encouraged all Americans to visit the government's flu-specific Web site, flu.gov

In addition, Secretary Sebelius outlined the government's intentions for minimizing the impact of H1N1. The H1N1 vaccine, if it is found to be safe and effective, will be purchased by the federal government, she said, and medical and scientific experts will help prioritize vaccination efforts and "get the shots in the arms of the people who need them most." A vaccine is currently being evaluated in clinical trials, and safety and effectiveness information should be available this month, she said. If the vaccine is found to be safe and effective, it should be available in limited amounts in October. Based on current evidence, likely high-risk groups that would be the first candidates for the H1N1 vaccine might include younger adults with comorbid conditions, children, and pregnant women.

Federal grants for state health departments to help with preparedness are available, Secretary Sebelius also announced. She added that $90 million will be available for hospitals to help prepare for the potential surge.

The Department of Homeland Security is focusing on the importance of maintaining essential services if widespread illness contributes to widespread absenteeism, Secretary Napolitano said. She stressed the need to "make sure that plans are in place so the functions of government continue," and encouraged state and local leaders to host their own local flu preparedness summits.

Because the 2009-H1N1 virus has disproportionately affected children, it is important to "get clear guidance out early," to schools, said Secretary Duncan. School-closing decisions should be made at the local level, on a school-by-school basis, and only as a last resort, he said.

Secretary Napolitano said that even if the 2009-H1N1 flu is less severe than expected, the procedures being put in place will improve the public health system for future emergencies.

BETHESDA, MD — The most likely scenario involving the influenza A (H1N1) virus this fall is that young people in schools will be disproportionately affected, said Dr. Anne Schuchat, director of the National Center for Immunization and Respiratory Diseases at the Centers for Disease Control and Prevention.

"We might need to offer interventions to people who aren't used to getting even a seasonal influenza vaccine," Dr. Schuchat said during a breakout session on vaccine preparation and distribution at an H1N1 Influenza Preparedness Summit sponsored by the National Institutes of Health.

Final recommendations for prioritizing H1N1 vaccination are expected to come from the CDC's Advisory Committee on Immunization Practices. In the meantime, the CDC's H1N1 Vaccine Task Force has developed a guidance document with a best-case planning scenario, so clinicians have some idea what might unfold if the number of H1N1 viral infections surges in the fall.

The document describes likely target populations and presents ideas for where and how the H1N1 vaccines could be administered.

Students and staff associated with schools, children aged 6 months and older, child care center staff, and health care workers would be among those on the high-priority list in the likely event that the vaccine's availability is limited. In a best-case scenario, students would be vaccinated at schools and child care centers, and health care workers would be vaccinated in their work environments.

The goal in any emergency is to "keep our children safe and keep them learning," Arne Duncan, secretary of the Department of Education said at the summit's morning session. School closings are a last resort, and more guidance is needed at the local level to help schools make informed decisions about what level of illness merits a closing. However, "most school districts have developed good emergency plans," he added.

WASHINGTON — No significant differences in neonatal outcomes were found among premature infants of women who had spinal anesthesia versus general anesthesia for cesarean delivery, based on the results of a study of 78 deliveries.

Most data on anesthesia and elective C-sections come from studies of term infants, said Dr. Robin Russell and colleagues at the John Radcliffe Hospital in Oxford, England. Data from one recent review of premature infants suggested that neonatal mortality risk was greater with spinal anesthesia than with general anesthesia, the researchers noted.

In this study, Dr. Russell and associates reviewed information from 78 women who were delivered at less than 33 weeks' gestation at a single hospital (69 singleton and 9 twin deliveries); the average age of the women was 31 years. The results were presented in a poster at the annual meeting of the Society for Obstetric Anesthesia and Perinatology.

Spinal anesthesia (SA) was used in 58 cases, general anesthesia (GA) in 18 cases, and an epidural in 2 cases. The researchers compared the outcomes for the SA and GA cases based on Apgar scores and umbilical blood gas levels.

Overall, Apgar scores were not significantly different between the spinal and general anesthesia groups. The median 1-minute Apgar score was 8 in the SA group (range, 2-10) and 7 in the GA group (range, 3-9), and the median 5-minute Apgar scores were 8 in the SA group and 9 in the GA group.

Measures of umbilical venous gases were available for 49 SA deliveries and 15 GA deliveries, and measures of umbilical arterial gases were available for 51 SA deliveries and 13 GA deliveries. Based on these measures, there were no significant differences between the groups.

In addition, the birth weights were similar between the two groups, and no significant differences were observed in the health of the infants at 28 days or 3 months of age.

The results contrast with findings from previous research, but the study was limited by its small size and retrospective design, the researchers said. “Further work is needed to determine the optimal mode of anesthesia for cesarean section in premature infants,” they wrote. The investigators reported that they had no financial conflicts to disclose.

WASHINGTON — The intensity of women's labor pain at the time of neuraxial anesthesia placement didn't influence the mode of delivery, based on data from a study of 555 nulliparous women.

No previous study has addressed whether timing of neuraxial anesthesia with regard to the degree of the patient's pain has an impact on the mode of delivery, Dr. Yaakov Beilin said in a poster at the annual meeting of the Society for Obstetric Anesthesia and Perinatology.

In this study, Dr. Beilin and Diana H. Mungall, both of Mount Sinai Hospital in New York, reviewed data from term, nulliparous women who presented to the labor floor of a single hospital between July 2005 and September 2008. Pain scores at the time of neuraxial analgesia placement were determined using a scale of 0-10 and divided into three groups: low (0-3), moderate (4-6), and high (7-10).

The cesarean section rate was 41%, 36%, and 34%, in the low-, moderate-, and high-pain groups, respectively; the differences were not significant.

Similarly, the operative delivery rate (which included cesarean plus instrumental assisted vaginal delivery) was 49%, 45%, and 45% in the low-, moderate-, and high-pain groups, respectively; these values were not significantly different. And the vaginal delivery rate of 51%, 55%, and 55% for the low-, moderate-, and high-pain groups, respectively, were not significantly different.

The results were limited by the retrospective nature of the study, but the data suggest that neuraxial analgesia can be safely placed in women with varying degrees of labor pain, Dr. Beilin said.

The researchers had no financial conflicts to disclose.

CHICAGO — A history of foodborne infections nearly triples the risk of inflammatory bowel disease, based on data from a population-based study of nearly 40,000 adults.

“We have seen increased incidence of both colitis and Crohn's disease in recent years,” said Dr. Henrik Nielsen of Aalborg (Denmark) Hospital. The pathogenesis of inflammatory bowel disease remains uncertain, Dr. Nielsen said at the annual Digestive Disease Week. Previous studies have suggested a role for environmental factors, including infections, but few of these studies have included long-term follow-up data.

Dr. Nielsen and his colleagues used laboratory registries from 1991 to 2003 to identify 13,148 adults with a history of Salmonella or Campylobacter gastroenteritis, as well as 26,216 controls without a history of these infections. The researchers followed the study population for up to 15 years, with an average follow-up period of 7.5 years.

A first-time diagnosis of inflammatory bowel disease (IBD) during the follow-up period was reported in 107 individuals with a history of Salmonella or Campylobacter infections, compared with 73 controls. The risk of IBD was independent of age and sex, and it was similar for both pathogens. In the group with the history of infections, the odds ratio for IBD was 2.9 during the entire follow-up period and 1.9 if the first year after infection was excluded.

“We documented both short-term and long-term increased risk of IBD following confirmed infections,” Dr. Nielsen said. The study could not prove causality because of its retrospective nature, but the results may contribute to a better understanding of the etiology of IBD as more research is done, he added.

The findings also emphasize the importance of food safety for disease prevention, Dr. Nielsen said at a press conference. The increased volume of imported foods and changes in food production may create more challenges for safe food handling, he said.

Dr. Nielsen had no financial conflicts to disclose.

None of 26 health care workers infected with the novel influenza A (H1N1) virus fully followed the Centers for Disease Control and Prevention's recommended infection control practices, based on data from the CDC's Morbidity and Mortality Weekly Report presented at a press briefing on June 18.

“The single most important thing is that infectious patients be identified at the front door,” said Dr. Michael Bell of the CDC's National Center for Preparedness, Detection, and Control of Infectious Diseases. “Identifying them up front is essential to let health care personnel know that they should be doing the things that we recommend,” he said.

The CDC investigators determined that 13 (50%) of the 26 cases were contracted in health care settings, with 12 cases of transmission from patients to health care providers and 1 case of transmission from one health care provider to another.

A total of 11 providers of the 12 cases of patient-to-provider transmission reported their use of protective equipment when caring for a patient infected with the H1N1 virus. None reported always using gloves, gowns, and either a mask or an N95 respirator. Only three said they always wore a mask or N95 respirator, five said they always wore gloves, and none said they used eye protection.

The CDC's recommendations for health care personnel include staying home when ill; washing hands frequently; and using protective gear including surgical masks, N95 respirators, gloves, and surgical gowns, as well as eye protection.

The results suggest that health care providers aren't over-represented among reported cases of the H1N1 virus so far. The data emphasize the need for health care facilities to adhere to infection control recommendations, identify and triage potentially infectious patients, provide infection control resources, and train staff in infection control practices, the CDC researchers noted.

The study was limited by several factors, however, including potential recall bias, the small number of cases, and the lack of information about several infection control practices, including hand hygiene.

Data on additional cases in health care providers are under review, Dr. Bell said.

The complete report on the novel influenza A (H1N1) cases in the 26 health care workers will be available in the CDC's June 19 Morbidity and Mortality Weekly Report (2009;58:641-5).

Transmission of the H1N1 virus in the United States is expected to continue throughout the summer and increase in the fall, Dr. Daniel Jernigan, a medical epidemiologist in the CDC's Influenza Division, said during the briefing.

The CDC has posted H1N1 guidance for summer camps on its Web site, Dr. Jernigan said. “It's important than aspirin not be used in children with influenza-like illness,” he added, because of the potential for complications.

The CDC investigators determined that 13 (50%) of the 26 cases were contracted in health care settings, with 12 cases of transmission from patients to health care providers and 1 case of transmission from one health care provider to another.

A total of 11 providers of the 12 cases of patient-to-provider transmission reported their use of protective equipment when caring for a patient infected with the H1N1 virus. None reported always using gloves, gowns, and either a mask or an N95 respirator. Only three said they always wore a mask or N95 respirator, five said they always wore gloves, and none said they used eye protection.

The CDC's recommendations for health care personnel include staying home when ill; washing hands frequently; and using protective gear including surgical masks, N95 respirators, gloves, and surgical gowns, as well as eye protection.

The results suggest that health care providers aren't over-represented among reported cases of the H1N1 virus so far. The data emphasize the need for health care facilities to adhere to infection control recommendations, identify and triage potentially infectious patients, provide infection control resources, and train staff in infection control practices, the CDC researchers noted.

The study was limited by several factors, however, including potential recall bias, the small number of cases, and the lack of information about several infection control practices, including hand hygiene.

Data on additional cases in health care providers are under review, Dr. Bell said.

The complete report on the novel influenza A (H1N1) cases in the 26 health care workers will be available in the CDC's June 19 Morbidity and Mortality Weekly Report (2009;58:641-5).

Transmission of the H1N1 virus in the United States is expected to continue throughout the summer and increase in the fall, Dr. Daniel Jernigan, a medical epidemiologist in the CDC's Influenza Division, said during the briefing.

The CDC has posted H1N1 guidance for summer camps on its Web site, Dr. Jernigan said. “It's important than aspirin not be used in children with influenza-like illness,” he added, because of the potential for complications.

Stimulant use was significantly associated with sudden, unexplained deaths in children and adolescents in a study of more than 500 children, but the data are not sufficient to change clinical prescribing practices, Food and Drug Administration officials said in a press briefing.

“It's hard to characterize the results as reassuring, but we didn't find them threatening,” said Dr. Robert Temple, director of the Office of Drug Evaluation I at the agency's Center for Drug Evaluation and Research.

Previous studies suggest that stimulants increase the risk of cardiovascular events, including sudden death, in children who are already at risk for heart problems, Dr. Temple said.

But few data exist on the impact of stimulant use in children without known underlying risk factors, he noted.

In this study, Madelyn S. Gould, Ph.D., of Columbia University in New York, and her colleagues compared stimulant use in 564 children aged 7-19 years who died suddenly from no known health problems, with stimulant use in 564 children aged 7-19 years who died as passengers in motor vehicle accidents.

Accident victims were chosen because they provide a control population of children who died suddenly and whose death was not caused by a known health problem. Children with a known history of heart problems were excluded from the study (Am. J. Psychiatry 2009 June 15 [doi: 10.1176/appi.ajp.2009.09040472]).

The researchers found that 10 (1.8%) children who died suddenly of unexplained causes were taking stimulants, compared with 2 (0.4%) children who died suddenly in car accidents. This difference was statistically significant after controlling for multiple variables, but the study was limited by several key factors, including a lack of complete postmortem blood work on the car accident victims, the researchers wrote.

A case-control study cannot prove causality, Dr. Temple added. “The reason for our cautious interpretation is that everything depends on whether the people who died were or were not taking an amphetamine,” he said, adding that the researchers depended primarily on the memories of people involved with the accident victims.

“We were unable to conclude that the data affect the overall risk and benefit profile of the stimulant medications,” said Dr. Temple.

He advised clinicians who treat children with stimulants to adhere to the current labeling recommendations and to monitor the children closely. “We continue to advise people to look at these children for any evidence of an underlying cardiac disease.”

WASHINGTON — Approximately 87% of large, high-volume emergency departments “board” admitted patients for more than 2 hours, based on the latest estimates from the National Hospital Ambulatory Medical Care Survey of 337 emergency departments.

Large emergency departments—defined as those that handle more than 50,000 visits per year—make up only 18% of all EDs in the United States, but they manage approximately 44% of all ED visits, Linda McCaig of the Centers for Disease Control and Prevention said at a workshop sponsored by the Institute of Medicine.

Ms. McCaig shared ED estimates for items that were added to the 2007 National Hospital Ambulatory Medical Care Survey (NHAMCS) hospital induction interview in the wake of the 2006 IOM report on emergency care in the United States.

The report raised concerns about overcrowding, fragmentation of care, lack of disaster preparedness, and the need for better emergency care for children.

The NHAMCS was designed to collect, analyze, and share information about the health care in emergency departments and outpatient medical departments. The data are collected from a national sample of hospitals across the United States, excluding federal, military, and Veterans Affairs facilities.

Data are taken from patient record forms, which are completed by hospital staff based on instructions from the CDC.

Overall, 63% of EDs board patients, including 83% of medium-sized EDs (20,000-50,000 visits per year) and 39% of small EDs (fewer than 20,000 visits per year).

Just over half (51%) of all EDs reported having a designated inpatient bed coordinator to help manage patient flow, including 71% of large EDs, 63% of medium EDs, and 34% of small EDs.

One-third of all EDs in the United States don't use any type of electronic medical records, including 18% of large EDs, 26% of medium EDs, and 54% of small EDs, Ms. McCaig said.

These NHAMCS data provide an example of how EDs are responding to the recommendations from the 2006 IOM report, which include creating a coordinated, regionalized system for emergency care and putting an end to the practice of boarding ED patients and diverting ambulances.

“This meeting and the two that will follow in the next few months are an opportunity, 3 years later, to revisit the committee's recommendations, to assess what progress we have made in achieving the committee's overall vision of a regionalized, coordinated, and accountable emergency care system,” said Dr. Arthur Kellermann, a professor and associate dean for health policy at Emory University in Atlanta, who served as the workshop chair.

WASHINGTON — Exposure to environmental asthma triggers at home was significantly associated with an increased risk of asthma-related hospitalizations in children younger than 4 years, compared with older children, based on data from 306 children up to 18 years old.

The percentage of hospitalizations for asthma in younger children also rose significantly with the number of home triggers, said Elizabeth Banda of the University of Illinois at Chicago.

Ms. Banda and her colleagues reviewed data from children with asthma enrolled in an asthma prevention program. The children were divided into three age groups: 0-4 years, 5-11 years, and 12 and older. The researchers collected data on hospitalizations and on the indoor allergens in each child's home via questionnaires.

Compared with older children, asthma hospitalizations in children aged 0-4 years were more than three times as likely to be associated with smoke, molds, or dampness; more than four times as likely to be associated with basement use and rodents; and more than five times as likely to be associated with roaches and clutter. The results were presented in a poster at the annual meeting of the American Academy of Allergy, Asthma, and Immunology.

Also, in children 0-4 years of age, the risk of asthma hospitalization was 9 times greater if they were exposed to five to six of these home conditions, compared with zero to four, and nearly 16 times greater if they were exposed to more than six.

The results were limited by the small sample size, cross-sectional design, and a lack of information about the degree of exposure to indoor environmental allergens. The findings suggest that younger children may be at greater risk because they spend more time in the home being exposed to indoor environmental triggers, compared with older children, the researchers said.

The study was supported by Merck Childhood Asthma Network Inc. Ms. Banda said she had no financial conflicts to disclose.

None of 26 health care workers infected with the novel influenza A (H1N1) virus fully followed the Centers for Disease Control and Prevention's recommended infection control practices, based on CDC data presented at a press briefing.

“The single most important thing is that infectious patients be identified at the front door,” said Dr. Michael Bell of the CDC's National Center for Preparedness, Detection, and Control of Infectious Diseases. “Identifying them up front is essential to let health care personnel know that they should be doing the things that we recommend,” he said.

The CDC investigators determined that 13 (50%) of the 26 cases were contracted in health care settings, with 12 cases of transmission from patients to health care providers and 1 case of transmission from one health care provider to another.

A total of 11 providers of the 12 cases of patient-to-provider transmission reported their use of protective equipment when caring for a patient infected with the H1N1 virus. None reported always using gloves, gowns, and either a mask or an N95 respirator. Only three said they always wore a mask or N95 respirator, five said they always wore gloves, and none said they used eye protection.

The CDC's recommendations for health care personnel include staying home when ill, washing hands frequently, and using protective gear including surgical masks, N95 respirators, gloves, and surgical gowns, as well as eye protection.

The results suggest that health care providers aren't overrepresented among reported cases of the H1N1 virus so far.

The data emphasize the need for health care facilities to adhere to infection control recommendations, identify and triage potentially infectious patients, provide infection control resources, and train staff in infection control practices, the CDC researchers noted.
