MedicalResearch.com: What is the background for this study?

Response: Adolescence is a time when teens begin to take charge of their health, but it is also a time when they can be prone to health risk behaviors, such as insufficient physical activity, poor sleep, and substance use. We were interested in whether using an electronic health risk screening tool in primary care settings could improve healthcare and health for adolescents.  The tool was designed to provide screening as well as motivational feedback directly to adolescents, in addition to clinical decision support for the healthcare clinician.  We conducted a trial with 300 adolescent patients where one group received the screening tool prior to their health checkup, and the other group received usual care.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Our study emphasizes the importance of team work and real-time communication in a quality-improvement project within the neonatal intensive care unit (NICU) setting.

Through bedside huddles, weekly reviews of apparent cause analysis reports reducing the frequency of X-rays and the creation of an Airway Safety Protection Team, we were able to focus not only on  reducing unintended extubations, but also on the quality-improvement project’s effect on our staff. Adhering to simple quality principles enabled us to ensure that all members of our staff were heard and had a positive effect on the progress of our project. This allowed us to implement and sustain a series of simple changes that standardized steps associated with securing and maintaining an endotracheal tube (ET). Unintended extubations are the fourth-most common adverse event in the nation’s NICUs. Continual monitoring via this quality-improvement project allowed us to intervene when our rates increased and further pushed our unintended extubation rate downward. Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response:  Although e-cigarette aerosols are commonly perceived to be “harmless water vapors” they contain numerous potentially harmful chemicals including volatile organic compounds like formaldehyde, nicotine, heavy metals, and ultrafine particulates. Non-users can be exposed to these chemicals through secondhand exposure.

We found that in the US 4.9% of adults who lived in a household with children were current e-cigarette users. Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Childhood body fat may be affected by patterns of fetal and infant weight change. Children born small for gestational age (SGA) tend to have infant growth acceleration, whereas those born large for gestational age (LGA) tend to have infant growth deceleration. Little is known about fetal and infant growth patterns affecting visceral, liver, and pericardial fat, which are strongly associated with cardiometabolic disease in later life.

We assessed in a large population cohort study whether fetal and infant weight change was associated with not only general, but also organ fat at school age. We observed that fetal and infant weight change patterns were both associated with childhood body fat, but weight change patterns in infancy tended to have larger effects. Fetal growth restriction followed by infant growth acceleration was associated with increased visceral and liver fat.  Continue reading

How Long Does Protection from DTaP Vaccination Last?

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Most high-income countries now use acellular pertussis vaccines (called DTaP, which are sub-unit vaccines based on purified antigens of the bacterium Bordetella pertussis) to protect children against pertussis. Although clinical trials demonstrated the short-term effectiveness of DTaP vaccines, there was a growing concern that the duration of protection they conferred was not very long. Those concerns were mostly based on the results of a number of epidemiological studies, which showed that the relative risk of contracting pertussis increased substantially over time, typically by 20–40% every year since last vaccination.

Although such increases seem high, it was not immediately obvious how to interpret them—the more so because pertussis epidemiology is complex.

In our study, we developed mathematical models of pertussis epidemiology to try to understand what the results of recent epidemiological studies really meant about the effectiveness and the duration of protection of DTaP vaccines. The most interesting—and perhaps counterintuitive—finding of our study was that those results are fully consistent with highly effective DTaP vaccines, which confer long-term protection. This is a consequence of the fact that pertussis is highly contagious and that the immunity conferred by DTaP, though very high, is not perfect.    Continue reading

Early Childhood Infections Associated With Eating Disorders In Adolescence

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Our study provides novel insight into the relationship between the immune system and eating disorders characterized by chronic restriction (e.g., anorexia nervosa) and binge eating and/or purging (e.g., binge eating disorder, bulimia nervosa). These findings also add to the growing body of literature linking the immune systems broadly and mental disorders.

We found that infections in early childhood were associated with an increased risk of anorexia nervosa, bulimia nervosa, and other eating disorders such as binge eating disorder in adolescence. These relationships appear to be both time and dose-dependent, meaning that the onset of eating disorder diagnosis is greatest in the first three months following the infection, and the more infections, the greater the risk.    Continue reading

MedicalResearch.com: What is the background for this study?

Response: Unintentional suffocation is the leading cause of injury deaths among infants under one year of age in the US. 82% of these deaths are attributed to accidental suffocation and strangulation in bed. The Sudden Unexpected Infant Death Case Registry was established by the Centers for Disease Control and Prevention (CDC) in 2009 to collect data on sudden unexpected infant deaths (SUID) to better understand trends and characteristics associated with these deaths. Data from 10 states, which account for about one-third of all US SUID cases, are captured in the Registry.

The CDC developed the Case Registry classification system in 2014 to differentiate SUID cases into several groups; explained suffocations with unsafe sleep factors is one of those categories, and the subject of this study. We analyzed infant deaths (children under one year of age) that occurred from 2011-2014 among states participating in the registry at the time of the study (Arizona, Colorado, Georgia, Louisiana, Michigan, Minnesota, New Hampshire, New Jersey, New Mexico, and Wisconsin). Among the 1812 cases in the Registry from 2011-2014, 250 (14%) were classified as suffocation. The remaining cases were classified as unexplained SUID.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: In 2009, the WIC program changed the food packages participants receive to better align them with federal dietary guidelines. These changes included the addition of fruits, vegetables, and whole grains; a reduction in the amount of dairy and juice; and a calibration in formula amounts to match infants’ age and needs.

We found that this change in the food package was associated with a 10-12% lower obesity risk at age 4 years among children who participated in WIC in Los Angeles County continuously from birth until age 4. Continue reading

Dr. Rosinger

Asher Y Rosinger, PhD, MPH
Assistant Professor of Biobehavioral Health and Anthropology

Pennsylvania State University

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Sugar-sweetened beverage consumption has been linked to many negative health conditions, such as weight gain, dental caries, and type 2 diabetes. Previous research found that when you replace sugar-sweetened beverages (SSBs) with water intake then total energy intake goes down. We wanted to know how many calories from SSBs children consume when they drink water or not since sugar-sweetened beverages are often used as a replacement for water. SSB intake has been falling among children over the last 15 years, but there are still pockets and sub-populations that have high consumption levels. It is critical to identify which kids are particularly at risk for high SSB intake since this can lead to these negative health effects.

Overall we found that kids that did not consume any plain water (from tap or bottled water) consumed almost twice as many calories and percent of total calories from sugar-sweetened beverages than kids that consumed water. And for the sample overall that translated to nearly 100 extra calories on a given day.  Continue reading

MedicalResearch.com: What is the background for this study?

Response: Lead exposure, especially in children, in any amount is harmful. Lead poisoning is a growing global environmental health problem with increasing lead-related diseases, disabilities, and deaths.  While exposure to lead in US children, in general, has significantly declined in the last three to four decades certain sub-groups of US children such as African Americans, immigrants and resettled refugees, and those from lower socioeconomic backgrounds are still vulnerable to environmental lead exposure.

Previous studies among resettled refugee children in the United States had found 4- to 5-times higher prevalence of elevated blood lead level (EBLL) when compared to US-born children. However, most of the studies were conducted when EBLL was defined as blood lead level ≥ 10 µg/dL. In 2012, the US Centers for Disease Control and Prevention changed the reference value for EBLL to ≥ 5 µg/dL. Moreover, because the countries of origin for US resettled refugees change over time, it is important to have epidemiologic studies that provide the current information on EBLL among these vulnerable new US immigrant children.

Using blood lead level data from the post-resettlement medical screening, our study examined the prevalence of elevated blood lead level at the time of resettlement among former refugee children who were settled in the state of Ohio from 2009-2016. We had a large and diverse sample (5,661 children from 46 countries of origin) of children for the study, which allowed us to assess EBLL in children from several countries of origin that had not been previously studied.

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Exposure to lead is dangerous and has been banned from use in residential dwellings. However, residual sources of lead still exist. Few studies have examined pediatric lead poisoning between public (NYCHA) and private housing units, and no recent studies performed in New York City. Our study used retrospective chart analysis of routine child lead testing to examine the difference in blood lead levels between the two housing types.

Our data showed that children seen in our health centers who lived in New York City public housing had significantly lower mean blood lead levels and fewer children were found with levels over the CDC reference range of 5 μg/dL compared to children who lived in private housing.  Continue reading

Response: The Stanford Pigmented Lesion and Melanoma and Program and Pediatric Dermatology Division participated in the long-term management of children, adolescents and young adults (<25 years of age) with melanoma and atypical melanocytic neoplasms, including atypical Spitz tumors (ASTs) that may be histopathologically challenging to differentiate from true melanoma.

Over a 23-year period, we have observed increased racial-ethnic diversity in young patients with these diagnoses, especially in the presentation of young individuals with darker skin phenotypes and more clinically amelanotic (nonpigmented) lesions compared to patients with lighter skin.  Continue reading

TRAP: Traffic Related Air Pollution Linked to Millions of Pediatric Asthma Cases Worldwide

Ploy Pattanun Achakulwisut, PhD
Postdoctoral Scientist in Climate change, Air pollution, and Public Health
Milken Institute School of Public Health (Anenberg Group
The George Washington University, D.C 

MedicalResearch.com: What is the background for this study?

Response: Dozens of epidemiological studies have found positive and generally statistically significant associations between long-term exposure to traffic-related air pollution (TRAP) and asthma development in children. The evidence is most robust for nitrogen dioxide (NO2), a major component of and commonly used surrogate for the complex TRAP mixture. Recent reviews conducted by the US Environmental Protection Agency and Health Canada concluded that there is “likely a causal relationship” between long-term NO2 exposure and pediatric asthma development.

Using NO2 as a proxy for TRAP, our study provides the first global estimate of the number of new asthma cases among children that are attributable to traffic pollution, using fine spatial-scale global datasets that can resolve within-city and near-roadway NO2 exposures.

Is There a Risk of Bleeding With Ibuprofen After Tonsillectomy ?

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Pediatric tonsillectomy is a commonly performed procedure, representing the second most common ambulatory surgery performed on children in the United States, with over half a million children undergoing the surgery annually.  A major concern for surgeons, patients, and their families is the issue of postoperative pain control as pain can last up to 10-14 days after surgery, be quite severe, and result in readmission to the hospital or ED visits for medications and dehydration.

In young children and children with sleep apnea we cannot safely administer narcotic pain medications at home.  This leaves limited options for pain control, including acetaminophen and ibuprofen.  However, there are concerns that ibuprofen could potentially increase bleeding risk after surgery because of its effects on platelet function in the blood.  At baseline, the risk of postoperative hemorrhage within the first two weeks after tonsillectomy is around 4.5%, with about 1-1.5% of children requiring a return to the operating room to control severe bleeding.  Our study set out to show that the risk of severe postoperative bleeding when ibuprofen is given for 9 days after tonsillectomy was not increased compared with the bleeding risk when acetaminophen was administered instead.

Our study could not conclude that the risk of bleeding is no different when ibuprofen is used, and was suggestive that the bleeding risk may actually be higher. Continue reading

Extremely Low Gestational Age Neonates May Benefit From Delayed Cord Clamping

MedicalResearch.com: What is the background for this study?

Response: There is no physiological rationale for clamping the umbilical cord immediately after birth. In moderate (32+0 weeks-33+6 weeks) and late preterm infants (34+0 to 36+6), delayed cord clamping reduces the need for blood transfusions, leads to circulatory stability and improves blood pressure.

However, the information on the association of delayed cord clamping with outcomes for extremely low gestational age neonates (22-28 weeks of gestation) is limited.

MedicalResearch.com: What is the background for this study?

Response: The wellbeing and development of children is strongly influenced by parents’ physical and psychosocial health. Parents of children with chronic illness, in particular, are susceptible to poor sleep, and previous studies have found major sleep impairments among parents of children with ventilator dependency and cystic fibrosis, but few studies have examined sleep patterns among parents of children with more common chronic illnesses like atopic dermatitis (also known as eczema).

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: There has been a global surge in vitamin D deficiency happening in parallel with an increase in prevalence of childhood asthma, which suggests that low maternal vitamin D levels during pregnancy may increase asthma risk in the child.

Due to that we conducted a randomized double-blinded controlled trial within the Danish COPSAC2010 cohort (www.copsac.com) of 7-fold (2,800 IU/d) vs. standard dose (400 IU/d) of vitamin D supplementation from pregnancy week 24 aiming to reduce offspring asthma risk. At age 3, we observed a non-significant 24% reduced risk of recurrent asthma-like symptoms, ie. recurrent wheeze, in the high-dose vitamin D group. In the current study, we followed 545 of the 581 children in the study till age 6, where an asthma diagnosis can be established and observed no effect of the high-dose vitamin D supplement on the child’s risk of asthma.

Prof. Morgan

Prof. Angela Morgan PhD
NHMRC Practitioner Fellow and
Leads the Speech and Language Group
Murdoch Children’s Research Institute

MedicalResearch.com: What is the background for this study? What are the main findings? 

Response: Approximately 5% of school-aged children have a communication impairment that affects speech, language, or both. There are many subtypes of speech sound disorders, but the most severe is  (CAS), which impacts sequencing of speech movements. Childhood apraxia of speech  occurs in around 1 in 1000 children. In persistent cases of CAS, speech cannot easily be understood throughout life. Although CAS is rare, unravelling its neurobiological causes is likely to identify brain networks crucial to more common and less severe forms of speech disorders.

Here we provide comprehensive speech and neuroimaging data on a large novel family where one parent and 11 children presented with features of childhood apraxia of speech. Brain MRI scanning revealed changes in core parts of the brain responsible for speech production. Even though CAS manifests as a problem with talking, we found disruptions in an underlying pathway of the brain normally associated with language (the meaning and grammar of what we say), rather than speech production. Our findings identify disruption of the dorsal language stream as a novel finding in developmental speech disorders. Overall, our data confirm the early role of this stream in auditory-to-articulation transformations.  Continue reading

Viaskin Peanut May Offer First Epicutaneous Treatment for Peanut Allergy

Dr. Green

Todd Green MD 
Vice President, Medical Affairs North America

University of Pittsburgh School of Medicine

MedicalResearch.com: What is the background for this announcement? What is Viaskin Peanut?

Response: Peanut allergy is one of the most common food allergies and can cause severe, potentially life-threatening allergic reactions, including anaphylaxis. Unfortunately, there are no FDA-approved treatment options for peanut or other food allergies – leaving patients with avoidance and readiness to manage reactions to accidental exposures as their only option.

Viaskin Peanut uses epicutaneous immunotherapy or EPIT, a method of delivering biologically active compounds to the immune system through the skin. Patients receive about 1/1,000th of a peanut with each daily dose of peanut protein – the equivalent of one peanut every three years – which activates the immune system with very minimal exposure.

In February 2019, DBV announced that its planned resubmission of the Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for Viaskin Peanut in the treatment of peanut-allergic children 4 to 11 years of age is anticipated in the third quarter of 2019.

DBV is working diligently on its resubmission package, bringing us one step closer to providing an FDA-approved treatment for peanut-allergic children and their families. Viaskin Peanut previously received Breakthrough and Fast Track designations for the treatment of peanut-allergic children from the FDA in 2015 and 2012, respectively.

MedicalResearch.com: What is the background for this study?

Response: The variability of the onset age of puberty is the subject of many studies in numerous disciplines; nonetheless, the timing of puberty remains an enigma. The conventional paradigm is that the time of onset of puberty is genetically determined even though genome-wide association studies explain only a very low percentage of the physiologic variability. It is commonly believed, therefore, that many environmental factors interfere with the genetics of timing of puberty.

On the other hand, children grow toward an adult height that is the standardized average of parents’ height called “target height”. That is why children are usually similar in height to parents. This targeted growth process is evident especially in children whose height percentile in childhood is different from their target height percentile (we called this difference the “height gap”). It is known that the timing of puberty is associated with adult height: earlier puberty causes shorter adult height and vice versa. We hypothesized that the targeted process of growth involves adaptation of the age of onset of puberty in accordance with the height gap. Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Gonococcal ophthalmia neonatorum, or GON, is a severe infection of the eye that can occur in babies born to women who have gonorrhea. If left untreated, GON can cause serious problems, including blindness, that can appear as soon as 24 hours after delivery.

Fortunately, there are effective treatments available that can prevent GON in newborns. The U.S. Preventive Services Task Force reviewed the most current research on the benefits and harms of ocular prophylaxis—which is applying antibiotic ointment to the babies’ eyes at birth—to prevent GON.

We found that, if applied within 24 hours after birth, the ointment is very effective at preventing gonococcal ophthalmia neonatorum and the problems it causes. Therefore, we are recommending that clinicians provide this preventive service for all newborns.  Continue reading

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: Parents are reporting that screen time is one of their major concerns, so we wanted to find out more about how large of a role screen time was playing on children’s developmental outcomes. We were especially interested in the long-term impact of screens, which is why we followed children over time, from ages 2 to 5 and repeatedly assessed both screen time use and children’s achievement of developmental milestones.

There are three main findings:

  1. Our study revealed that on average children were viewing screens for 2.4, 3.6 and 1.6 hours per day at two, three and five years of age, respectively. This means that the majority of the participants in our sample are exceeding the American Academy of Pediatrics’ guideline of no more than one-hour of high quality programming per day, for children aged 2-5 years.
  2. We found statistically significant, albeit small effects suggesting that greater amounts of screen time at two and three years predict poorer child outcomes at three and five years, respectively. Thus, screen time has a lasting influence on children’s development.
  3. The opposite pattern was not observed. That is, we did not find evidence that children showing poor performance in terms of achieving developmental milestones were more likely to be place in front of screens to help cope with their potentially challenging behaviors.

MedicalResearch.com: What should readers take away from your report?

Response: When used in excess, screen time can have consequences for children’s development. We should think of screens like we do junk food, in small doses it’s ok, but in excess, it is problematic. But it’s never too late to make a change to the way digital technology is used in the home. Media plans can be developed as a family to manage media in the home and determine how often devices will be used, as well as when and where they will be used.

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response:  In this study, we asked about total hours of screen time and, as a result, we can’t determine if context matters (i.e., screens viewed with caregivers or not), or if there are certain types of digital mediums or devices that are worse than others (e.g., interactive screens, gaming consoles, or streaming media). Thus, it will be important to decipher in future research whether co-viewing screens with a caregiver, for example, dampens associations between screen time and delays in children’s development and whether certain types of screens are more or less detrimental for children’s development.

Psychiatric Problems Related to Lead Exposure Detected As Early As Age 11

MedicalResearch.com Interview with:
Aaron Reuben, MEM

Duke University, Durham, North Carolina

MedicalResearch.com: What is the background for this study? What are the main findings?

(1)  Study members with greater lead exposure in childhood tended to endorse more psychiatric symptoms when assessed for psychiatric disorders in adulthood (between 18 and 38 years of age).

  1. These individuals tended to report more internalizing (e.g., depression, anxiety) and thought disorder (e.g., OCD, schizophrenia, mania) symptoms.
  2. Compared to other findings from this sample, the associations reported in this article are similar to those reported for lead and IQ, and are stronger than those reported for lead and criminal offending.
    1. Informants who knew Study members well reported higher levels of difficult adult personality traits among Study members with greater lead exposure in childhood.
    2. Specifically, Study members with greater blood lead levels at age 11 were rated as more neurotic, less agreeable, and less conscientious by 38 years of age.
    3. These personality traits have been previously linked to a number of poor life outcomes, including greater psychopathology, worse physical health, less job satisfaction, and troubled interpersonal relationships
  3. Psychiatric problems related to lead exposure could be detected as early as 11 years of age. In the 1980’s, parents and teachers of children with higher blood-lead levels had described them as displaying more antisocial behavior, hyperactivity, and negative emotions (e.g., sadness, anxiety).

Program Addresses Racial Inequities in Breastfeeding in Southern US

MedicalResearch.com Interview with:

Dr-Anne Merewood

Anne Merewood PhD MPH
Director, Center for Health Equity, Education, and Research
Associate Professor of Pediatrics, Boston University School of Medicine
Associate Professor of Community Health Sciences
Boston University School of Public Health

MedicalResearch.com: What is the background for this study? What are the main findings?

Response: CHAMPS (Communities and Hospitals Advancing Maternity Practices) worked with hospitals and communities across the southern US to implement the Baby-Friendly Hospital Initiative and decrease racial inequities in breastfeeding rates.

We found that indeed this program significantly reduced the gap between Black and White breastfeeding initiation rates in the 31 hospitals studied, by almost 10%. 

MedicalResearch.com: What should readers take away from your report?

Response: Hospitals and communities can work together in areas where racial disparities are extreme and breastfeeding rates are low, to improve hospital practices around the time of birth. These changes will have an impact on racial gaps in breastfeeding, and will bring more humane and evidence-based care to thousands of women, now and in the future, as the changes are solidified. Improved practices level the playing field for underprivileged groups. 

MedicalResearch.com: What recommendations do you have for future research as a result of this work?

Response: Future research should assess the implementation model to see if it can be applied in other settings. Also, future research needs to examine how well these changes can be sustained.

Zika: Simple General Movement Assessment Tool Can Predict Babies at Risk of Developmental Problems

MedicalResearch.com: What is the background for this study?

Response: Our study used a very simple evaluation called GMA (General Movement Assessment tool) which checks baby movements at approximately 3 to 5 months of age.

We examined 111 babies exposed to maternal illness during the Zika epidemic in Brazil and 333 control babies without this exposure by GMA at 3 months  and then tested them through standard neurodevelopmental tests at the age of 12 months.

We found that this simple evaluation, which consists of filming a baby lying down on their back for one minute and studying their movements worked extremely well in predicting which babies would or would not have future problems in their neurodevelopment. The study advances knowledge in the area because a simple one minute video of a baby can predict neurodevelopment, something that is extremely hard to determine in young babies.  This is true even in places where sophisticated brain scans are available. By identifying which babies are at risk of developmental problems early on, professionals can rapidly refer these babies to  stimulation programs when they are very young, which increases their chances of having better outcomes. Because the brains of young children respond much better  to stimulation, the timing of interventions to improve their development is very important, that is why they need to be identified early.

College Students at Increased Risk of Meningitis

MedicalResearch.com: What is the background for this study?

Response: College freshman living in residence halls, though not college students overall, have previously been identified as being at increased risk for meningococcal disease. However, these evaluations were conducted in the 1990s when rates of disease were higher, serogroup C was the predominant cause of disease, and before the availability of quadrivalent meningococcal conjugate (MenACWY) or serogroup B meningococcal (MenB) vaccines.

MenACWY vaccine is routinely recommended for all adolescents at age 11 years and 16 years, as well as unvaccinated or undervaccinated college freshmen living in residence halls. MenB vaccine is not routinely recommended for all adolescents or college students, but may be administered to persons aged 16-23 years, with the preferred age of 16-18 years, based on clinical decision-making. Meningococcal vaccines are also recommended during an outbreak, and in recent years MenB vaccines have been used during multiple outbreaks on college campuses.

In this evaluation, we aimed to describe the current epidemiology of meningococcal disease among college-aged young adults in the United States.

MedicalResearch.com: What is the background for this study?

Response: Group B Streptococcus (GBS) is a leading cause of serious illness such as meningitis and sepsis in infants. Among infants, there are two main types of GBS disease. Early-onset GBS disease occurs during the first week of life and late-onset GBS disease occurs from the first week through three months of life. Rates of early-onset disease in the United States have decreased significantly since the 1990s through widespread implementation of intrapartum antibiotic prophylaxis (IAP) guidelines. However, IAP does not prevent late-onset disease. Maternal immunization represents a nonantibiotic strategy to prevent both early and late-onset disease. Multivalent polysaccharide-protein conjugate vaccines are under development against GBS capsular types, with candidate vaccines in phase I and II trials.

Active Bacterial Core surveillance (ABCs) conducts active surveillance for early and late-onset GBS disease among infants in select counties of 10 states, covering about 10% of live births across the United States. We analyzed data from early and late-onset GBS cases identified from ABCs between 2006 and 2015 to describe their epidemiology, incidence trends, and associated strain characteristics.
