HPV vaccination uptake and administration from 2006 to 2016 in a commercially insured population of the United States.

BACKGROUND: Human papillomavirus (HPV) infection can cause various cancers and can be prevented through vaccination. The American Cancer Society (ACS) has set an HPV vaccination completion target in 13-year-old children to 80% by 2026. While HPV vaccine coverage (proportion ever vaccinated) estimates are available, annual uptakes (proportion initiating vaccine in a year) in the United States (U.S.) are not well-known. METHODS: We analyzed MarketScan® claims database to assess HPV vaccination uptakes in the U.S. among the 9- to 26-year-olds in 2006-2016. The annual uptake was the ratio of the number of enrollees who had a first record of an HPV vaccine during the year, and the number of enrollees of similar age and sex that year. RESULTS: Uptake was below 1% among children turning 9 and 10 years old during the year. Since 2009 among female and since 2013 among males, the annual uptake has been the highest in those turning 13 years old (19.7% among females and 17.6% among males in 2016). Catch-up vaccination among older adolescents and young adults increased after Advisory Committee for Immunization Practices (ACIP) recommendations, but eventually slowed down as more younger persons were vaccinated. Most young adolescents were vaccinated by pediatricians, whereas young adult women were predominantly vaccinated by obstetricians/gynecologists and young adult males by family physicians. While only about half of the adolescents had well-check visits, the majority of those who initiated HPV vaccination had one the same year. CONCLUSION: Continued increase in uptake is needed to reach the ACS 2026 goals.

Talking trash: Perspectives on community environmental health in the Dominican Republic.

A safe and healthy natural and built environment is fundamental to children's health and represents a significant determinant of community well-being. We aimed to identify and prioritize environmental health concerns within resource-poor neighborhoods in the Dominican Republic using free-listing and semi-structured focus groups composed of parents and caregivers in the perirural community of Consuelo, Dominican Republic. Transcripts were coded and relevant themes identified using qualitative content analysis. Demographic data and information regarding trash disposal practices were also collected. Participants described common health concerns, including respiratory infections, asthma, vector-borne illnesses, and diarrheal diseases and linked them to environmental hazards in their communities, such as air quality and sanitation. Interventional priorities that emerged included reduction of trash accumulation and trash burning as well as improvement of sanitation facilities.

Chest Radiographic Findings and Outcomes of Pneumonia Among Children in Botswana.

BACKGROUND: Chest radiography is increasingly used to diagnose pneumonia in low-income and middle-income countries. Few studies examined whether chest radiographic findings predict outcomes of children with clinically suspected pneumonia in these settings. METHODS: This is a hospital-based, prospective cohort study of children 1-23 months of age meeting clinical criteria for pneumonia in Botswana. Chest radiographs were reviewed by 2 pediatric radiologists to generate a consensus interpretation using standardized World Health Organization criteria. We assessed whether final chest radiograph classification was associated with our primary outcome, treatment failure at 48 hours, and secondary outcomes. RESULTS: From April 2012 to November 2014, we enrolled 249 children with evaluable chest radiographs. Median age was 6.1 months, and 58% were male. Chest radiograph classifications were primary endpoint pneumonia (35%), other infiltrate/abnormality (42%) or no significant pathology (22%). The prevalence of endpoint consolidation was higher in children with HIV infection (P = 0.0005), whereas endpoint pleural effusions were more frequent among children with moderate or severe malnutrition (P = 0.0003). Ninety-one (37%) children failed treatment, and 12 (4.8%) children died. Primary endpoint pneumonia was associated with an increased risk of treatment failure at 48 hours (P = 0.002), a requirement for more days of respiratory support (P = 0.002) and a longer length of stay (P = 0.0003) compared with no significant pathology. Primary endpoint pneumonia also predicted a higher risk of treatment failure than other infiltrate/abnormality (P = 0.004). CONCLUSIONS: Chest radiograph provides useful prognostic information for children meeting clinical criteria for pneumonia in Botswana. These findings highlight the potential benefit of expanded global access to diagnostic radiology services.

Treatment Failures and Excess Mortality Among HIV-Exposed, Uninfected Children With Pneumonia.

BACKGROUND: Human immunodeficiency virus (HIV)-exposed, uninfected (HIV-EU) children are at increased risk of infectious illnesses and mortality compared with children of HIV-negative mothers (HIV-unexposed). However, treatment outcomes for lower respiratory tract infections among HIV-EU children remain poorly defined. METHODS: We conducted a hospital-based, prospective cohort study of N = 238 children aged 1-23 months with pneumonia, defined by the World Health Organization. Children were recruited within 6 hours of presentation to a tertiary hospital in Botswana. The primary outcome--treatment failure at 48 hours--was assessed by an investigator blinded to HIV exposure status. RESULTS: Median age was 6.0 months; 55% were male. One hundred fifty-three (64%) children were HIV-unexposed, 64 (27%) were HIV-EU, and 20 (8%) were HIV-infected; the HIV exposure status of 1 child could not be established. Treatment failure at 48 hours occurred in 79 (33%) children, including in 36 (24%) HIV-unexposed, 30 (47%) HIV-EU, and 12 (60%) HIV-infected children. In multivariable analyses, HIV-EU children were more likely to fail treatment at 48 hours (risk ratio [RR]: 1.83, 95% confidence interval [CI]: 1.27-2.64, P = .001) and had higher in-hospital mortality (RR: 4.31, 95% CI: 1.44-12.87, P = .01) than HIV-unexposed children. Differences in outcomes by HIV exposure status were observed only among children under 6 months of age. HIV-EU children more frequently received treatment with a third-generation cephalosporin, but this did not reduce the risk of treatment failure in this group. CONCLUSIONS: HIV-EU children with pneumonia have higher rates of treatment failure and in-hospital mortality than HIV-unexposed children during the first 6 months of life. Treatment with a third-generation cephalosporins did not improve outcomes among HIV-EU children.

Association of respiratory viruses with outcomes of severe childhood pneumonia in Botswana.

BACKGROUND: The highest incidence of childhood acute lower respiratory tract infection (ALRI) is in low- and middle-income countries. Few studies examined whether detection of respiratory viruses predicts ALRI outcomes in these settings. METHODS: We conducted prospective cohort and case-control studies of children 1-23 months of age in Botswana. Cases met clinical criteria for pneumonia and were recruited within six hours of presentation to a referral hospital. Controls were children without pneumonia matched to cases by primary care clinic and date of enrollment. Nasopharyngeal specimens were tested for respiratory viruses using polymerase chain reaction. We compared detection rates of specific viruses in matched case-control pairs. We examined the effect of respiratory syncytial virus (RSV) and other respiratory viruses on pneumonia outcomes. RESULTS: Between April 2012 and August 2014, we enrolled 310 cases, of which 133 had matched controls. Median ages of cases and controls were 6.1 and 6.4 months, respectively. One or more viruses were detected from 75% of cases and 34% of controls. RSV and human metapneumovirus were more frequent among cases than controls, but only enterovirus/rhinovirus was detected from asymptomatic controls. Compared with non-RSV viruses, RSV was associated with an increased risk of treatment failure at 48 hours [risk ratio (RR): 1.85; 95% confidence interval (CI): 1.20, 2.84], more days of respiratory support [mean difference (MD): 1.26 days; 95% CI: 0.30, 2.22 days], and longer duration of hospitalization [MD: 1.35 days; 95% CI: 0.20, 2.50 days], but lower in-hospital mortality [RR: 0.09; 95% CI: 0.01, 0.80] in children with pneumonia. CONCLUSIONS: Respiratory viruses were detected from most children hospitalized with ALRI in Botswana, but only RSV and human metapneumovirus were more frequent than among children without ALRI. Detection of RSV from children with ALRI predicted a protracted illness course but lower mortality compared with non-RSV viruses.

Relationship of training to self-reported competency and care of adolescents in an African health care setting.

PURPOSE: Adolescent medicine is not a recognized specialty in most African countries and African healthcare providers receive little adolescent-specific training. We explored the association between training, self-reported competence, and clinical practice related to adolescent health in an African setting. METHODS: A total of 119 healthcare providers of various disciplines who work with adolescent patients in Francistown, Botswana were surveyed regarding their adolescent-specific training, self-reported competence, and counseling practices. Self-reported competence and practices related to counseling adolescents about sexual activity, alcohol and/or drug use, human immunodeficiency virus (HIV)-specific issues, and mental health were explored. RESULTS: In all, 50.4% of respondents had received HIV training with an adolescent-specific component. Fewer had received adolescent-specific training outside the context of HIV prevention and management. Respondents were significantly more likely to report higher competence for all items except for counseling adolescents about depression and anxiety if they had received any adolescent-specific training. Respondents who reported higher competence were significantly more likely to report more frequent counseling of their adolescent clients. CONCLUSIONS: Our study suggests that adolescent-focused training is important for ensuring that adolescents receive counseling when presenting for routine healthcare in our setting. The mental health needs of adolescents do not seem to be adequately addressed by current training.

Nutritional status of children after a food-supplementation program integrated with routine health care through mobile clinics in migrant communities in the Dominican Republic.

The objective of this study was to compare acute and chronic undernutrition rates before and after the introduction of a food-supplementation program as an adjunct to routine health care for children of migrant workers in the Dominican Republic. The cross-sectional study was conducted in five rural communities in the Dominican Republic. Children 18 years and younger were eligible if they received routine health care from local mobile clinics. Data were obtained before (2005) and after (2006) initiation of a food-supplementation program. chi(2) or Fisher exact tests were used for analysis. Among 175 children in 2005, 52% were female, and 59% were < 5 years of age (mean age = 5.3 years). Among 148 children in 2006, 48% were female, and 57% were < 5 years of age (mean age = 5.6 years). Acute undernutrition rates decreased from 40% to 23% (P = 0.001) after initiation of the food-supplementation program. Rates of chronic undernutrition decreased from 33% to 18% after the initiation of the food-supplementation program (P = 0.003). Food supplementation in the context of routine health-care visits improved the nutritional status of children, and it warrants further exploration as a way to reduce childhood undernutrition in resource-scarce areas.

Risk factors for intrathoracic tuberculosis in children from economic migrant populations of two Dominican Republic bateyes.

OBJECTIVE: The objective of the current study was to identify risk factors for intrathoracic tuberculosis among children living in migrant populations in the Dominican Republic. DESIGN: Cross-sectional study. SETTING: Dominican Republic bateyes, economic migrant communities of Haitian origin. PARTICIPANTS: Children 18 months to 18 years of age. MAIN EXPOSURE: Unpasteurized milk consumption. OUTCOME MEASURES: Probable or possible intrathoracic tuberculosis. Probable intrathoracic tuberculosis was defined as any child with a tuberculin skin test >or=10 mm (or >5 mm in the presence of a known immunocompromising condition or household contact with intrathoracic tuberculosis) or malnutrition in the setting of an abnormal chest radiograph with features of tuberculosis or lymph node disease. The diagnosis of "possible intrathoracic tuberculosis" was assigned if an abnormal chest radiograph had features that did not meet the definition of "probable intrathoracic tuberculosis." RESULTS: Probable or possible tuberculosis was diagnosed in 83 (20.8%) of 400 children. Unpasteurized milk consumption was identified as an independent risk factor for intrathoracic tuberculosis (adjusted odds ratio, 3.2; 95% confidence interval: 1.4-7.4) even after adjusting for Bacille Calmette-Guérin vaccination, household size, tuberculosis contacts and age and under varying assumptions about children diagnosed with "possible" tuberculosis. CONCLUSIONS: Our data raise the possibility that the high prevalence of tuberculosis in the Dominican Republic bateyes may be attributable to Mycobacterium bovis rather than Mycobacterium tuberculosis infection.
