Item Adolescent Women with Congenital Heart Disease: Self-Reported Reproductive Health Discussions with Health Care Providers(Elsevier, 2022) Katz, Amy J.; Lyon, Shannon; Farrell, Anne G.; Srivastava, Nayan; Wilkinson, Tracey A.; Shew, Marcia L.; Pediatrics, School of MedicineStudy objective: This study evaluated self-reported discussions with health care providers (HCPs) among adolescent and young adult (AYA) women with congenital heart disease (CHD). Design: Data were collected through a one-time survey of AYA women. Setting: Participants were recruited from pediatric cardiology clinics. Participants: AYA women with CHD, ages 14-21 (N = 107) INTERVENTIONS: None MAIN OUTCOME MEASURES: Questionnaires assessed adolescent characteristics and specific HCP discussions regarding transmissibility of a cardiac condition to the infant, risk of pregnancy, and hormonal contraception. Outcome measures were self-reported discussions with HCPs about these reproductive health topics. Results: Mean age was 16.8 years (SD = 2.1). Self-reported reproductive health discussions were infrequent, including discussions on transmissibility of a heart condition to their offspring (37%), risk of pregnancy to their offspring (34%), risks of pregnancy to their health (46%), and risks of hormonal contraception given their heart condition (21%). Reported discussions were most commonly with a cardiologist. Conclusions: AYA women with CHD reported limited discussions about reproductive health topics important to those with CHD. Lack of appropriate and timely counseling could lead to poor maternal and child health outcomes. Targeted interventions that improve reproductive health discussions between HCPs and AYA women with CHD are needed to close critical information and service gaps.Item Association of Chlamydia trachomatis infection with redetection of human papillomavirus after apparent clearance(Oxford, 2013-11) Shew, Marcia L.; Ermel, Aaron C.; Weaver, Bree A.; Tong, Yan; Tu, Wanzhu; Kester, Laura M.; Denski, Cheryl; Fortenberry, J. Dennis; Brown, Darron R.; Pediatrics, School of MedicineBACKGROUND: Persistent infection with oncogenic human papillomavirus (HPV) is associated with an increased risk of cervical malignancy. Redetection of type-specific HPV after a period of nondetection may be caused by reactivation of a low-level persistent infection. Little is known about factors associated with type-specific HPV redetection. METHODS: For a longitudinal cohort of adolescent women with frequent behavioral and sexually transmitted infection (STI) information (every 3 months), Cox proportional hazard models were used to assess the influence of sexual behaviors and STIs on the redetection of oncogenic or high-risk HPV infections. RESULTS: A total of 210 type-specific high-risk HPV detection episode periods were identified in this longitudinal cohort; 71 (33.8%) were characterized by a period of nondetection followed by redetection. Chlamydia trachomatis (hazard ratio [HR], 3.14; 95% confidence interval [CI], 1.44-6.86) was associated with redetection; redetection was >2 times more likely with each additional self-reported sex partner in the past 3 months (HR, 2.26; 95% CI, 1.35-3.78). CONCLUSIONS: This study demonstrates the role of C. trachomatis and number of recent sexual partners in type-specific HPV redetection. Given that persistent oncogenic HPV infections are associated with cancer-related outcomes, understanding the potential role of such factors in the pathogenesis of HPV-related outcomes is important.Item Considerations for Child Cancer Survivors and Immunocompromised Children to Prevent Secondary HPV-associated Cancers(Wolters Kluwer, 2020-09) Imburgia, Teresa M.; Shew, Marcia L.; Gravitt, Patti E.; Katzenellenbogen, Rachel A.; Pediatrics, School of MedicineSurvivors of childhood cancer and other immunocompromised children are at high risk for the development of secondary Human Papillomavirus (HPV)-associated cancers. In this overview, the authors examine the epidemiology of vaccine efficacy, the natural history of HPV infections, and accelerated HPV-associated cancer development in these populations. The authors highlight the opportunities for preventive care and future research directives.Item The Effects of Progestin-Only Hormone Treatment on QT Interval in the Adolescent Female(Elsevier, 2021-01) Kean, Adam C.; Ayers, Mark D.; Farrell, Anne G.; Kean, Kelly A.; Brooks, Patricia W.; Shew, Marcia L.; Pediatrics, School of MedicineWe describe the effect of exogenous progestin on the corrected QT interval (QTc) in adolescent females. In post-menarcheal females, <18 years old, we compared QTc in milliseconds (ms) on ECG evaluations in those taking exogenous progestin vs those who are not. There were 40 controls and 21 treated participants. The age range was 10–17 years. There were no differences between the groups with regard to race, height, weight, BMI, or blood pressure. In the controls, the mean QTc was 403 ±19 milliseconds (ms) vs. 397 ±15 ms in those treated (p = 0.22). Those on progestin therapy had a shorter QTc by the same magnitude difference (six ms) as the hormonal naïve group in the adult literature. We report no adverse effects of progestin associated with QTc prolongation and a trend suggesting a decreased QTc in a population of post-menarcheal adolescent females.Item Human papillomavirus infection-related cancer risk for kidney transplant recipients during adult life can be reduced by vaccination during childhood and adolescence(Frontiers Media, 2022-11-30) Nailescu, Corina; Shew, Marcia L.; Pediatrics, School of MedicineMalignancies are found between the first three reasons of mortality in pediatric and adult kidney transplant recipients, who overall have disproportionately higher rates of cancer compared to the general population, including human papillomavirus (HPV)-related genital, anal and oropharynx region cancers. Therefore, preventing HPV in this patient population is extremely important. HPV-vaccine was demonstrated to prevent HPV infection in individuals with intact immune systems. In addition, recent data reported less precancerous HPV lesions and cervical cancers with use of HPV vaccine. Since HPV is a sexually transmitted virus that is typically acquired shortly after the onset of sexual activity, it is best to administer the HPV vaccine immunization prior to the onset of sexual activity. This article reviews the epidemiology and pathophysiology of the HPV infection, as well as its role in the development of HPV-related pre-cancerous lesions and cancers in both general population and kidney transplant recipients. The focus is on the most effective primary prophylactic strategy, which is the HPV vaccination. The particularities of HPV vaccination strategies in kidney transplant recipients are compared to the general population. In addition, the article analyzes the various causes of suboptimal HPV immunization rates in kidney transplant candidates and recipients and discusses vaccination optimization strategies that can be applied during childhood and adolescence to reduce the burden of HPV-related disease states and cancer among adult kidney transplant recipients.Item Human papillomavirus-related cancer risk for solid organ transplant recipients during adult life and early prevention strategies during childhood and adolescence(Wiley, 2022-11) Nailescu, Corina; Ermel, Aaron C.; Shew, Marcia L.; Pediatrics, School of MedicineMalignancies are among the top three causes of patient death in pediatric and adult kidney transplant (KT) recipients. Solid organ transplant (SOT) recipients, including KT individuals, experience more cancer compared with the general population, including human papillomavirus (HPV)-related anogenital and oropharyngeal cancers. This article describes the epidemiology, pathophysiology and natural history of the HPV infection in both the general population and in SOT recipients, as well as its role in the development of HPV-related pre-cancerous lesions and cancers. Emphasis is given to the primary prevention strategy, HPV vaccination in SOT recipients, and its particularities compared with the general population. Secondary prevention strategies in SOT recipients are discussed and compared with the general population, highlighting cervical cancer screening needs within SOT populations. The article emphasizes how these primary and secondary HPV prevention strategies applied during childhood and adolescence by the pediatric transplant professionals, can lower the burden of HPV-related cancers for SOT recipients in subsequent years, during their adult life.Item Menstrual Dysfunction and Treatment Among Adolescents With Congenital Heart Disease(Elsevier, 2020) Leroy-Melamed, Maayan; Katz, Amy; Shew, Marcia L.; Pediatrics, School of MedicineStudy Objective This study describes menstrual dysfunction and treatment among adolescent and young adult (AYA) females with congenital heart disease (CHD). Design Data collected from a 1-time survey completed by AYA females (and mothers if AYA unable). Setting Participants were recruited from pediatric cardiology clinics. Participants Female AYA with CHD, aged 14-21 years (N = 114). Interventions None. Main Outcome Measures The questionnaire assessed sexual and reproductive health (SRH) concerns, behaviors, and management. Outcome measures were self-reported menstrual complaints, use of over-the-counter (OTC) pain relief medications for dysmenorrhea, reported visits with a clinician for a menstrual problem, and reported use of hormones for menstrual problems or birth control. Results Mean age was 17.0 years (SD = 2.2). The majority of participants (83%) reported 1 or more menstrual complaints (67.5% cramping, 42.1% irregular menses, 46.5% heavy periods), and 88% reported any history of taking OTC medications for pain relief. Increased menstrual complaints were not associated with level of cardiac complexity, reported transplantation, or reported use of hormonal contraception. However, 32% of participants reported use of hormonal contraception for menstrual dysfunction. Combined oral contraceptive pills (COCs) were the most common; 2 of these women carried contraindications to estrogen. Conclusions A large majority of AYA females with CHD reported menstrual dysfunction. Use of OTC medication for menstrual pain and inappropriate use of estrogen creates concerns that menstrual disorders may be unaddressed or addressed inappropriately. Thus, gynecological needs of adolescents with CHD may need to be specifically targeted by providers who feel comfortable with this population and their complex needs.Item Otolaryngologists and their role in vaccination for prevention of HPV associated head & neck cancer(Taylor & Francis, 2019) Shew, Matthew; Shew, Marcia L.; Bur, Andrés M.; Pediatrics, School of MedicineAs Otolaryngologists we have witnessed a rise in a new disease with human papilloma virus (HPV) associated oropharyngeal squamous cell carcinoma (OPSCC). As of 2018, HPV associated OPSCC has surpassed the incidence of HPV associated cervical cancer within the United States. Non-HPV related head and neck cancer is largely a preventable disease through avoidance of various environmental factors, and we have seen a significant decline in cancer rates through anti-tobacco campaigns and other public health efforts. Given the success of HPV vaccination campaigns and reduction in HPV associated cervical and other anogenital cancers, some would argue HPV OPSCC is largely a preventable disease through vaccination as well. The question remains is how do we as otolaryngologist, non-primary care providers yet surgeons for this disease, help to promote public health efforts to reduce HPV related OPSCC. Within this article, we discuss preliminary data that supports HPV vaccination with HPV related OPSCC and the ongoing needs by our profession to help support public efforts in reducing the burden of this HPV related cancer.Item Provider Attitudes, Preferences, and Practices Regarding Sexual and Reproductive Health for Adolescents and Young Adults with Sickle Cell Disease(Elsevier, 2021) Leroy-Melamed, Maayan; Jacob, Seethal; Shew, Marcia L.; Kazmerski, Traci M.; Pediatrics, School of MedicinePurpose: With improvements in life expectancy, adolescents and young adults (AYAs) with sickle cell disease (SCD) increasingly face sexual and reproductive health (SRH) concerns. As subspecialists often serve as primary care providers for those with chronic disease, this study examines pediatric SCD providers' practices and attitudes related to SRH of AYA women with SCD. Methods: We developed an adapted survey to identify SCD provider attitudes and practices in addressing menses, sexual activity, contraception, and pregnancy for their female patients. We electronically distributed this survey to the American Society of Pediatric Hematology/Oncology SCD interest group. We used descriptive statistics to analyze results. Results: A total of 78 pediatric SCD providers completed the survey. A majority (95%) rated SRH discussions as moderately important or higher, with 89% agreeing this care should be standardized. Most respondents reported discussing SRH, such as menses (78%), teratogenic medications (61%), and contraception (90%), with their female patients with SCD at least annually. Although most refer AYAs with SCD for birth control (83%), 39% endorsed a preferred method, with 33% of these favoring levonorgestrel intrauterine devices in this population and 40% injectable contraception. Approximately half of respondents (57%) reported that the use of combined hormonal contraceptives was unacceptable despite published guidelines that support potential benefits outweighing theoretical risk in AYAs with SCD. Conclusions: The range of SRH conversations and contraceptive recommendations for AYAs from pediatric SCD providers is broad. SCD providers and AYAs with SCD would benefit from improved evidence and educational resources related to contraception as well as coordinated SRH counseling.Item Redetection of human papillomavirus type 16 infections of the cervix in mid-adult life(Elsevier, 2018-06) Ermel, Aaron; Shew, Marcia L.; Imburgia, Teresa M.; Brown, Matt; Qadadri, Brahim; Tong, Yan; Brown, Darron R.; Medicine, School of MedicinePURPOSE: To assess whether HPV 16 originally detected in adolescent women can be redetected in adulthood. METHODS: A convenience sample of 27 adult women with known HPV 16 detection during adolescence was assessed for HPV 16 redetection. A comparison of the long control region (LCR) DNA sequences was performed on some of the original and redetected HPV 16 isolates. RESULTS: Median age at reenrollment was 27.5 years (interquartile range of 26.7-29.6). Reenrollment occurred six years on average after the original HPV 16 detection. Eleven of 27 women had HPV 16 redetected. Some of these HPV 16 infections had apparently cleared during adolescence. LCR sequencing was successful in paired isolates from 6 women; in 5 of 6 cases the redetected HPV 16 isolates were identical to those detected during adolescence, CONCLUSIONS: HPV 16 may be episodically detected in young women, even over long time periods. HPV 16 redetection with identical LCR sequences suggests low-level persistent infection rather than true clearance, although newly acquired infection with an identical HPV 16 isolate cannot be excluded. However, this study suggests that a new HPV 16-positive test in a clinical setting may not indicate a new infection.
