Cancer Prevention Education for Providers, Staff, Parents, and Teens Improves Adolescent Human Papillomavirus Immunization Rates.

OBJECTIVE: To develop a program to educate providers, office staff, patients, and parents on life-long cancer prevention strategies, including the use of human papillomavirus (HPV) vaccine to improve adolescent HPV vaccination rates. STUDY DESIGN: A 2-phase program was implemented at 6 pediatric practices across upstate New York. Phase 1 included provider and staff education regarding practice-specific vaccination challenges and discussion of the contents of a study-specific cancer-prevention booklet, which included HPV vaccine information. Throughout phase 2, the booklets were distributed to all adolescents and their parents during office visits over a 12-month period. Practice-specific, countywide, and statewide HPV vaccination rates were assessed before phase 1, and 6 and 12 months after the launch of phase 2. RESULTS: One year after implementing phase 2 in 6 practices, adolescent HPV vaccine series initiation increased by at least 10% in 3 practices, and at least 5% in 5 practices. Similarly, adolescent vaccine series completion rates increased by more than 10% in 3 practices. The percent change in vaccine series completion rates across all study sites postintervention ranged from 12% to 20% for 11- to 12-year-olds, and from 7% to 23% for 13- to 18-year-olds. CONCLUSIONS: Cancer prevention education targeting providers, office staff, patients, and parents was modestly effective for improving adolescent HPV vaccination rates.

Passive Immunization Strategies to Prevent Severe Respiratory Syncytial Virus Infection Among Newborns and Young Infants.

Newborns and young infants are at risk for severe respiratory syncytial virus (RSV) lower respiratory tract infection. Passive immunity is the mainstay of infection prevention in this cohort. Transplacental transfer of maternal antibodies provides the newborn with immediate protection from life-threatening infections, however, is dependent upon gestational age, birth weight, mother's age, recent maternal vaccination, maternal nutritional status, maternal immunocompetence and medical conditions, and placental integrity. Efficient transplacental transfer of RSV-neutralizing antibodies have led to the development and approval of maternal RSV immunization for the protection of the newborn. Additionally, administration of RSV-specific antibodies to infants leads to high serum titers of RSV-neutralizing antibodies and further protection from severe disease.

Local production of CCL3, CCL11, and IFN-γ correlates with disease severity in murine parainfluenza virus infection.

BACKGROUND: Using a murine model of parainfluenza virus infection (mPIV1 or Sendai virus; SeV), we compared the inflammatory responses to lethal and sub-lethal infections in inbred DBA/2 mice. METHODS: Mice were intranasally inoculated with either 1.6×10(3) or 1.6×10(5) infectious units (IU) of SeV or diluent control. Clinical data including daily weights, oxygen saturation, and lung function via whole body plethysmography were collected on days 0, 3-7, and 9-14. Clarified whole lung homogenates were evaluated for inflammatory markers by enzyme-linked immunoassay (ELISA). Data were analyzed using ANOVA or Student t-tests, as appropriate. RESULTS: Mice inoculated with 1.6×10(5) IU of SeV developed a lethal infection with 100% mortality by day 7, while mice inoculated with 1.6×10(3) IU developed a clinically significant infection, with universal weight loss but only 32% mortality. Interestingly, peak virus recovery from the lungs of mice inoculated with 1.6×10(5) IU of SeV did not differ substantially from that detected in mice that received the 100-fold lower inoculum. In contrast, concentrations of CCL5 (RANTES), CCL11 (eotaxin), interferon-γ, CXCL10 (IP-10), and CCL3 (MIP-1α) were significantly higher in lung tissue homogenates from mice inoculated with 1.6×105 IU (p < 0.05). In the lethal infection, levels of CCL11, interferon- γ and CCL3 all correlated strongly with disease severity. CONCLUSION: We observed that severity of SeV-infection in DBA/2 mice was not associated with virus recovery but rather with the levels of proinflammatory cytokines, specifically CCL11, interferon- γ and CCL3, detected in lung tissue in response to SeV infection.

Vaccine knowledge, attitudes, and recommendation practices among health care providers in New York State.

Community-wide vaccine uptake remains sub-optimal. Healthcare provider (HCP) vaccine recommendations influence patient vaccination; however, provider vaccine recommendation behavior is highly influenced by one's own vaccine attitudes and/or knowledge. We aim to describe vaccine knowledge, attitudes, and recommendation practices (KAP) among New York State HCPs. A survey to assess HCP KAP was developed and electronically distributed to NYS members of national medical organizations via their local chapter administrators. Descriptive statistical methods were used to define provider KAP. A total of 864 surveys were included, 500 (60%) and 336 (40%) primary and specialty care providers, respectively. Eighty-one percent (402/499) of primary care providers (PCPs) report encountering vaccine hesitant patients daily or weekly. Of the 500 PCPs who responded, only 204 (41%) stated strong agreement with confidence in their communications with vaccine hesitant patients. HCPs who correctly answered all four knowledge questions were more likely to self-report routine recommendations of standard vaccines to all patients when compared to those who correctly answered fewer questions (489/588 (83%) vs 135/241 (56%), p < .05). HCPs were more likely to routinely recommend standard vaccines to all patients if they also report initiating vaccine discussion (476/485 (98%) vs 148/344 (43%), p < .05) and reviewing and recommending vaccinations at each encounter (315/320 (98%) vs 308/508 (61%), p < .05). Vaccine hesitancy exists across healthcare specialties and provider roles. Focused interventions should include reaching all HCPs to promote vaccinations for disease prevention, tailoring messages to reduce HCP vaccine misperceptions, and increasing awareness of evidence-based office strategies known to facilitate immunizations.

HPV vaccine knowledge, attitudes, and practices among New York State medical providers, dentists, and pharmacists.

Healthcare provider vaccine knowledge and attitudes influence delivery of a strong vaccine recommendation. We aim to describe HPV vaccine knowledge, attitudes, and recommendation or discussion practices (KAP) among New York State medical providers, dentists, and pharmacists. A survey to assess providers' KAP was distributed electronically to NYS members of medical organizations. Descriptive and inferential statistical methods were used to characterize provider KAP. Responses from 1637 surveys were included, from 864 (53%) medical providers, 737 (45%) dentists, and 36 (2%) pharmacists. 59% (509/864) of medical providers responded that they recommend HPV vaccine to patients, with 390/509 (77%) strongly recommending vaccine at 11-12 years. Medical providers were more likely to report recommending HPV vaccine for children ages 11-12 years if they strongly agreed that HPV vaccine prevents cancer 326/391 (83%) vs 64/117 (55%) and responded that HPV vaccination does not increase the risk of unprotected sex (386/494 (78%) vs 4/15 (25%)) (p < .05). Less than 1/3 of dentists reported discussing HPV vaccine with 11-26-year-old females (230/737, 31%) and males (205/737, 28%) at least "sometimes." Dentists were more likely to answer that they routinely discuss HPV vaccine with children ages 11-12 years if they responded that HPV vaccination does not increase sexual activity (70/73 (96%) vs 528/662 (80%), p < .001). Few pharmacists reported discussing HPV vaccine with 11-26-year-old females (6/36 (17%)) and males (5/36 (14%)) at least "sometimes." Gaps in HPV vaccine knowledge among providers still exist and may influence vaccine attitudes and recommendation or discussion practices.

Epidemiology of RSV Bronchiolitis Among Young Children in Central New York Before and After the Onset of the COVID-19 Pandemic.

BACKGROUND: Respiratory syncytial virus (RSV) bronchiolitis is the leading cause of hospitalizations among infants in the United States. Unpredictability in RSV seasonality has occurred following the onset of the coronavirus disease 2019 (COVID-19) pandemic. Local surveillance networks can enhance the ability to appropriately time prophylaxis when exposure risk is highest. METHODS: A retrospective, cohort study was conducted to describe the epidemiologic patterns of RSV disease among outpatient, emergency department and inpatient encounters in children <5 years in Central New York before and after the onset of the COVID-19 pandemic. Local data were collected from October 2015 to January 2023 and compared to state-level data. Linear regression models were used to identify clinical and sociodemographic differences before and after the pandemic. RESULTS: Local variation in RSV seasonality was noted prior to the COVID-19 pandemic, however highly atypical circulation patterns appeared in the post-COVID-19 era. Since March 2020, patterns for local and state-defined RSV seasons have remained atypical (local season onset in 2021: week 27 and 2022: week 27; state season onset in 2021: week 31 and 2022: week 38). After adjusting for increases in testing, RSV bronchiolitis cases were not significantly different during pre- and post-pandemic eras. In comparison to the 2021 bronchiolitis season, the 2022 season had a higher proportion of RSV cases despite decreased testing. CONCLUSIONS: Temporal patterns for RSV have shifted during the COVID-19 pandemic. Local surveillance networks may be advantageous in trending community-level RSV activity to optimize prophylaxis administration. Changes in RSV testing patterns occurred throughout the study period and should be accounted for when describing infant and childhood RSV disease.

Etiologies of outpatient medically attended acute respiratory infections among young Ecuadorian children prior to the start of the 2020 SARS-CoV-2 pandemic.

BACKGROUND: Implementation of respiratory virus prevention measures requires detailed understanding of regional epidemiology; however, data from many tropical countries are sparse. We describe etiologies of ambulatory pediatric acute respiratory tract infections (ARTI) in Ecuador immediately preceding the onset of the SARS-CoV-2 pandemic. METHODS: Children < 5 years presenting to a designated study site with an ARTI were eligible. Informed consent was obtained. Demographic and clinical data were recorded. A nasopharyngeal swab was collected, processed, and analyzed using multiplex polymerase chain reaction (PCR) for common respiratory pathogens. Rhinovirus/enterovirus positive samples were further characterized by genomic sequencing. RESULTS: A total of 820 subjects were enrolled in the study between July 2018 and March 2020. A total of 655 (80%) samples identified at least one pathogen. Rhinoviruses (44%) were most common, followed by enteroviruses (17%), parainfluenza viruses (17%), respiratory syncytial virus (RSV) (15%), and influenza viruses (13%). Enterovirus D68 was the most common enterovirus detected and was among the leading causes of bronchiolitis. Seasonal RSV and influenza virus activity were different along the coast compared with the highlands. CONCLUSIONS: Ongoing regional surveillance studies are necessary to optimize available and emerging pathogen-specific preventative measures.

Cytomegalovirus sinusitis in a child with chronic myelogenous leukemia following bone marrow transplantation.

Cytomegalovirus (CMV) is a common opportunistic pathogen. CMV sinusitis has been described in acquired immunodeficiency syndrome (AIDS) patients, but not in other immune compromising conditions. In this report, we describe CMV sinusitis in a child with chronic myelogenous leukemia (CML) following bone marrow transplantation.

Epidemiology and Seasonality of Childhood Respiratory Syncytial Virus Infections in the Tropics.

Infections caused by respiratory syncytial virus (RSV) are a major cause of morbidity and mortality in young children worldwide. Understanding seasonal patterns of region-specific RSV activity is important to guide resource allocation for existing and future treatment and prevention strategies. The decades of excellent RSV surveillance data that are available from the developed countries of the world are incredibly instructive in advancing public health initiatives in those regions. With few exceptions, these developed nations are positioned geographically across temperate regions of the world. RSV surveillance across tropical regions of the world has improved in recent years, but remains spotty, and where available, still lacks the necessary longitudinal data to determine the amount of seasonal variation expected over time. However, existing and emerging data collected across tropical regions of the world do indicate that patterns of infection are often quite different from those so well described in temperate areas. Here, we provide a brief summary regarding what is known about general patterns of RSV disease activity across tropical Asia, Africa and South America, then offer additional country-specific details using examples where multiple reports and/or more robust surveillance data have become available.

Multi-component cancer prevention awareness program to improve adolescent HPV vaccine uptake.

OBJECTIVE: We introduced a multi-component cancer prevention awareness program to primary care practices across New York State to evaluate its impact on adolescent human papillomavirus (HPV) vaccination rates. METHODS: Eight pediatric and three family medicine practices were recruited to participate in this program. On-site training sessions were provided for all practice providers and staff to discuss the importance of HPV vaccine and cancer prevention and teach strategies for delivering a strong vaccine recommendation. Each practice received a study-specific booklet that included HPV vaccine information and other commonly provided cancer prevention guidance. These booklets were distributed to all adolescents and their parents during well visits over a one-year period. Practice specific and county-wide HPV vaccination rates were assessed before and 12 months after the program training session. RESULTS: One year after program initiation, aggregate data show statistically higher vaccine series initiation rates among 11-12 and 13-18-year-olds and higher vaccine series completion rates among 13-18-year-olds. The greatest and most consistent improvements were seen in vaccine initiation rates for the 11-12-year-old cohort. Disparities in vaccine uptake were observed by gender and medical specialty. CONCLUSION: Cancer prevention education targeting providers, office staff, patients, and parents, improved adolescent HPV vaccine series initiation rates.

Incidence of invasive community-onset Staphylococcus aureus infections in children in Central New York.

We determined the incidence of invasive community-onset Staphylococcus aureus infections, clinical characteristics, and antibiotic susceptibilities in 128 hospitalized children in central New York. The prevalence of invasive S aureus infections in our institution remained <1% between 1996 and 2006, although the proportion of methicillin-resistant S aureus infections significantly increased.

Medically Attended Outpatient Coronavirus Infections in Ecuadorean Children During the 20 Months Preceding Countrywide Lockdown Related to the SARS-CoV-2 Pandemic of 2020.

BACKGROUND: Human coronaviruses (HCoVs) cause respiratory tract infections during childhood manifesting as common colds, bronchiolitis, croup and pneumonia. In temperate geographies, HCoV activity peaks between December and March. The epidemiology and manifestations of HCoV infections have not been previously reported from Ecuador. METHODS: Children <5 years who presented with ≥2 symptoms consistent with an acute respiratory tract infection were eligible for enrollment. After obtaining informed consent, demographic data and details regarding the acute illness were recorded. Secretions collected with a nasopharyngeal swab underwent diagnostic testing using multiplex polymerase chain reaction. RESULTS: A total of 850 subjects were enrolled. A total of 677 (80%) tested positive for at least 1 pathogen, including 49 (7.2%) who tested positive for ≥1 HCoV type. HCoV-NL63 was the most frequent type detected (39%), followed by HCoV-OC43 (27%), 229E (22%) and HKU1 (12%). Nearly all subjects who tested positive for HCoV had nasal congestion or secretions (47/49; 96%). The most frequent syndromic diagnosis was common cold (41%), followed by bronchiolitis (27%). We found no association between the infecting HCoV type and subject's syndromic diagnosis (P > 0.05) or anatomic location of infection (upper vs. lower respiratory tract; P > 0.05). The 2018-2019 peak HCoV activity occurred from October to November; the 2019-2020 peak occurred from January to February. CONCLUSIONS: HCoVs were detected in ~7% of outpatient Ecuadorean children <5 years of age with symptoms of acute respiratory tract infection. The most frequently detected HCoV types, and the period of peak HCoV activity differed for the 2018-2019 and 2019-2020 seasons.

Clinical features, adenovirus types, and local production of inflammatory mediators in adenovirus infections.

BACKGROUND: Adenovirus infection manifests in many ways, with respiratory and gastrointestinal symptoms predominating. METHODS: We performed a retrospective chart review on children evaluated at our center who had a nasal wash culture positive for adenovirus. Archived nasal washes were retrieved. Polymerase chain reaction for 15 respiratory viruses was performed on these samples. Patients who were coinfected with another virus were excluded. Adenovirus typing was performed using polymerase chain reaction primers directed at the conserved hexon gene. Bead proteomics was used to measure concentrations of inflammatory mediators. RESULTS: Seventy-eight patients were infected only with adenovirus. The clinical diagnosis was upper respiratory infection in 60%, pneumonia in 18%, febrile seizure in 8%, and bronchiolitis in 6%. Subgroup-C and B1 infections were most common. Seventy percent of patients with upper respiratory infection and all 5 patients with bronchiolitis had a subgroup-C infection; pneumonia was caused by subgroup-B1 and C viruses. Compared with asymptomatic control patients, adenovirus infected patients had higher nasal wash concentrations of interleukin (IL)-1alpha, IL-6, inducible protein-10, macrophage inflammatory protein-1alpha, tumor necrosis factor alpha, monokine induced by gamma interferon, and interferon-alpha (P < 0.05). In addition, we found that IL-8 and IL-1alpha (P < 0.05) were higher in the nasal washes obtained from hospitalized patients than in nonhospitalized patients. CONCLUSIONS: Adenovirus infection causes an array of clinical disease and is associated with local production of several proinflammatory cytokines. The observation that nasal wash IL-8 and IL-1alpha concentrations were higher in patients requiring hospitalization suggests that these mediators contribute to disease severity.

A quality improvement education initiative to increase adolescent human papillomavirus (HPV) vaccine completion rates.

HPV vaccine uptake is low, nationwide. Quality improvement (QI) principles have the potential to change practice; however, not all providers are confident with QI skills. We developed an educational program designed to enhance QI skills and improve HPV vaccination rates. Five pediatric practices participated in the pilot initiative. Training consisted of presentations regarding QI methods, data tracking and analysis, and system changes to reduce missed opportunities. Monthly for 6 months, participants performed chart audits, captured data, printed run charts, and developed, implemented, and tracked interventions. Outcome measures included rates of HPV vaccine completion and missed opportunities. A second phase included eight different pediatric practices who received similar training. Outcome measures included rates of HPV vaccine initiation and completion. Over the 6 months, mean HPV vaccine completion rates increased (45% to 65%) and missed opportunities for HPV vaccination decreased (45% to 19%) in the pilot program. When the program was replicated in phase 2, an increase was seen in both HPV vaccine initiation (46% to 61%) and completion (62% to 94%) rates. Combining QI education with workflow-focused strategies was associated with a reduction in missed opportunities and a substantial increase in HPV vaccine completion rates.

Associations between population based voting trends during the 2016 US presidential election and adolescent vaccination rates.

BACKGROUND: Politics play a role in the dissemination of public health information, including immunization-related issues. We aim to describe relationships between HPV vaccination rates and state voting patterns during the 2016 US presidential election. METHODS: We classified each of the 50 states as either "Red" or "Blue," based on whether a higher proportion of the state's casted votes were for the Republican or Democratic nominee during the 2016 US presidential election. State-specific HPV, Tdap, and meningococcal vaccination rates were obtained from the 2016-National Immunization Survey-Teen. State socio-demographic factors and HPV vaccine legislation were obtained from the US Census Bureau and National Conference of State Legislatures. Vaccination rates and socio-demographic variables were compared using independent t-tests. Multiple linear regression compared vaccination rates between "Red" and "Blue" states, adjusting for percentage of both uninsured children and educational attainment. RESULTS: Compared to "Blue" states, "Red" states had significantly lower unadjusted HPV vaccine series initiation (56% vs 66%, p < 0.05) and completion (39% vs 50%, p < 0.05) rates; yet had similar rates of Tdap (88% vs 89%, p > 0.05) and meningococcal (79% vs 83%, p > 0.05) vaccinations. After adjusting for potential confounders, the regression-adjusted mean rate for HPV vaccine initiation and completion remained significantly lower for "Red" states compared to "Blue" states (57% vs 65%, p < 0.05, and 41% vs 48%, p < 0.05, respectively). CONCLUSION: HPV vaccination rates are associated with statewide-level voting patterns. Future interventions aimed at improving HPV vaccination rates should consider engaging local and national elected leaders to be proactive in disseminating accurate and authoritative immunization information.

Systemic calciphylaxis.

An 11-year-old male developed systemic calciphylaxis during induction therapy for acute lymphoblastic leukemia. His predisposing conditions were hypercalcemia, supplements for pamidronate-induced hypocalcemia and hypophosphatemia and renal insufficiency. He died of cardiorespiratory arrest on the 20th day of induction treatment. Autopsy revealed extensive calcium deposits in the heart, lungs and kidneys. He had diffused alveolar damage, acute tubular necrosis, chronic pancreatitis and marked hepatic steatosis. Systemic calcium deposition may progress rapidly in children with hypercalcemia of malignancy. Since pamidronate reduces mineral resorption from tissues, calcium and phosphate replacements increase systemic mineral deposits. Thus, mineral supplements should be considered only to combat symptoms.

Immunization attitudes and practices among family medicine providers.

OBJECTIVE: To describe immunization attitudes and practices among family medicine providers across New York State. METHODS: In this cross-sectional survey study, family medicine providers across New York State completed a questionnaire to assess vaccine beliefs and barriers and immunization practices. STATISTICAL ANALYSIS: Descriptive statistical methods were used to define provider characteristics, knowledge and vaccine practices. RESULTS: Completed questionnaires from 226 family medicine providers were included for analysis. As a group, 207/218 (95%) of providers who answered the question state they always recommend standard pediatric vaccines. Of the 209 providers who answered both questions, 47 (22%) state they always recommend standard pediatric vaccines but do not always recommend HPV vaccine to eligible 11-12 year-old patients. Only 75% of providers strongly disagreed with the statement 'vaccinating adolescents against HPV increases the likelihood of unprotected sex'. Even though 178/190 (94%) and 164/188 (87%) of surveyed family medicine providers reported recommending that their pregnant patients receive influenza vaccine and Tdap vaccine, respectively, only 134/185 (72%) routinely do so in their office. CONCLUSION: Most family medicine providers self-report always recommending standard pediatric vaccines, however only a minority are following ACIP recommendations. Educational sessions to update family medicine providers on ACIP recommendations and address individual provider concerns may improve provider vaccine confidence and uptake of vaccines by their patients.

"Being Persistent without Being Pushy": Student Reflections on Vaccine Hesitancy.

Our goal as pediatric educators is to graduate physicians who have witnessed effective approaches and have grasped the nuances of communication strategies between vaccine-hesitant families and health care providers. We identified vaccine hesitancy as a recurring topic in 19 of 304 medical student reflective narratives addressing an issue in professionalism or systems-based practice. We conducted content analysis on the narratives in order to gain a better understanding of student perceptions of visits in which they observed a provider discussing vaccine hesitancy with a parent. We identified four major themes: perceived effectiveness of provider-family communication, student reaction to the encounter, physician approach to vaccine hesitancy, and gaps in students' own knowledge. Most students described communication positively, despite only 4 of 19 observing eventual vaccine acceptance. Information regarding vaccines, vaccine delivery, and approaches to vaccine hesitancy needs to be introduced and enhanced in the educational curriculum of providers at all levels, including medical students, resident physicians, and attending physicians, in order to ensure that providers possess the comprehension and communication skills to ethically optimize vaccine uptake among patients.
