ABSTRACT
OBJECTIVE: To determine the validity of diagnostic hospital billing codes for complications of prematurity in neonates <32 weeks gestation. STUDY DESIGN: Retrospective cohort data from discharge summaries and clinical notes (n = 160) were reviewed by trained, blinded abstractors for the presence of intraventricular hemorrhage (IVH) grades 3 or 4, periventricular leukomalacia (PVL), necrotizing enterocolitis (NEC), stage 3 or higher, retinopathy of prematurity (ROP), and surgery for NEC or ROP. Data were compared to diagnostic billing codes from the neonatal electronic health record. RESULTS: IVH, PVL, ROP and ROP surgery had strong positive predictive values (PPV > 75%) and excellent negative predictive values (NPV > 95%). The PPVs for NEC (66.7%) and NEC surgery (37.1%) were low. CONCLUSION: Diagnostic hospital billing codes were observed to be a valid metric to evaluate preterm neonatal morbidities and surgeries except in the instance of more ambiguous diagnoses such as NEC and NEC surgery.

OBJECTIVE: The objective of this study was to describe the burden of adverse kidney and hypertension outcomes in patients evaluated by pediatric nephrology in a multidisciplinary survivorship clinic. STUDY DESIGN: Retrospective chart review of all patients followed up by nephrology in our multidisciplinary survivorship clinic from August 2013 to June 2021. Data included clinic blood pressure, longitudinal ambulatory blood pressure monitoring (ABPM), echocardiography, serum creatinine, and first-morning urine protein/creatinine ratios. For patients with multiple ABPMs, results of initial and most recent ABPMs were compared. RESULTS: Of 422 patients followed in the multidisciplinary cancer survivorship clinic, 130 were seen by nephrology. The median time after therapy completion to first nephrology visit was 8 years. The most common diagnoses were leukemia/myelodysplastic syndrome (27%), neuroblastoma (24%), and Wilms tumor (15%). At the last follow-up, 68% had impaired kidney function, 38% had a clinical diagnosis of hypertension, and 12% had proteinuria. There were 91 ABPMs performed in 55 (42%) patients. Patients with multiple ABPMs (n = 21) had statistically significant reductions in overall median blood pressure loads: systolic initial load 37% vs most recent 10% (P = .005) and diastolic load 36% vs 14% (P = .017). Patients with impaired kidney function were more likely to have received ifosfamide. Patients with hypertension were more likely to have received total body irradiation or allogeneic stem cell transplant. CONCLUSIONS: History of leukemia/myelodysplastic syndrome, neuroblastoma, and Wilms tumor was frequent among survivors seen by nephrology. There was significant improvement in cardiovascular measures with increased recognition of hypertension and subsequent treatment.

BACKGROUND: Neuroblastoma is the most common extracranial solid tumor in children. Those with high-risk disease are treated with multimodal therapy, including high-dose chemotherapy, stem cell transplant, radiation, and immunotherapy that have led to multiple long-term complications in survivors. In the late 1990s, consolidation therapy involved myeloablative conditioning including total body irradiation (TBI) with autologous stem cell rescue. Recognizing the significant long-term toxicities of exposure to TBI, more contemporary treatment protocols have removed this from conditioning regimens. This study examines an expanded cohort of 48 high-risk neuroblastoma patients to identify differences in the late effect profiles for those treated with TBI and those treated without TBI. PROCEDURE: Data on the study cohort were collected from clinic charts, provider documentation in the electronic medical record of visits to survivorship clinic, including all subspecialists, and ancillary reports of laboratory and diagnostic tests done as part of risk-based screening at each visit. RESULTS: All 48 survivors of BMT for high-risk neuroblastoma had numerous late effects of therapy, with 73% having between five and 10 late effects. TBI impacted some late effects significantly, including growth hormone deficiency (GHD), bone outcomes, and cataracts. CONCLUSION: Although high-risk neuroblastoma survivors treated with TBI have significant late effects, those treated without TBI also continue to have significant morbidity related to high-dose chemotherapy and local radiation. A multidisciplinary care team assists in providing comprehensive care to those survivors who are at highest risk for significant late effects.

Neural circuits in female rats are exposed to sequential estradiol and progesterone to regulate the release of luteinizing hormone (LH) and ultimately ovulation. Estradiol induces progesterone receptors (PGRs) in anteroventral periventricular nucleus (AVPV) kisspeptin neurons, and as estradiol reaches peak concentrations, neuroprogesterone (neuroP) synthesis is induced in hypothalamic astrocytes. This local neuroP signals to PGRs expressed in kisspeptin neurons to trigger the LH surge. We tested the hypothesis that neuroP-PGR signaling through Src family kinase (Src) underlies the LH surge. As observed in vitro, PGR and Src are co-expressed in AVPV neurons. Estradiol treatment increased the number of PGR immunopositive cells and PGR and Src colocalization. Furthermore, estradiol treatment increased the number of AVPV cells that had extranuclear PGR and Src in close proximity (< 40 nm). Infusion of the Src inhibitor (PP2) into the AVPV region of ovariectomized/adrenalectomized (ovx/adx) rats attenuated the LH surge in trunk blood collected 53 h post-estradiol (50 µg) injection that induced neuroP synthesis. Although PP2 reduced the LH surge in estradiol benzoate treated ovx/adx rats, activation of either AVPV PGR or Src in 2 µg estradiol-primed animals significantly elevated LH concentrations compared to dimethyl sulfoxide infused rats. Finally, antagonism of either AVPV PGR or Src blocked the ability of PGR or Src activation to induce an LH surge in estradiol-primed ovx/adx rats. These results indicate that neuroP, which triggers the LH surge, signals through an extranuclear PGR-Src signaling pathway.

AIMS: Our aim was to evaluate the predictive value of a battery of 10 non-invasive tests of cardiovascular structural and functional health on the future risk of cardiovascular morbid events. METHODS AND RESULTS: A total of 1900 asymptomatic adults concerned about their risk for cardiovascular disease underwent non-invasive assessment with 10 tests of vascular and cardiac structure and function. A disease score (DS) was calculated for each individual based on these 10 tests. Follow-up (mean 9.2 years) for cardiovascular morbidity and mortality was available for 1442 individuals (mean age 53.2 years, 48.2% women). Those in the lowest DS tertile (0-2) experienced 0.16 cardiovascular events per 100 patient-years (PY), those in the middle tertile (3-5) experienced 0.86 events per 100 PY, and those in the highest tertile (6+) experienced 1.3 events per 100 PY (p < .001). Sensitivity analysis, assuming a neutral effect of DS on projected events in subjects not followed, did not alter statistical significance. Risk assessment using the Framingham risk score (FRS) also predicted morbid events but the two methods differed in identifying individuals at high risk. The net reclassification index was improved by 0.11 (p = 0.01) when DS was added to FRS. CONCLUSIONS: Assessing the biological disease process in the arteries and heart of asymptomatic adults provides a guide to the risk of a future cardiovascular morbid event. Larger and longer studies are needed to determine whether risk factor algorithms, the severity of the biological process or some combination is the optimal method for identifying individuals in need of intervention to delay morbid events.

INTRODUCTION: While early enteral nutrition is generally preferred in critically ill patients, the optimal timing of feeding among refractory cardiac arrest patients is unknown. We examined the association between timing of enteral nutrition and patient survival and safety outcomes in patients with refractory out-of-hospital cardiac arrest (OHCA) who were treated with extracorporeal cardiopulmonary resuscitation (ECPR). METHODS: We performed a retrospective analysis of 142 consecutive patients presenting with OHCA due to ventricular fibrillation or ventricular tachycardia treated with ECPR and targeted temperature management (TTM). Neurologically favorable survival and clinical outcomes were compared between patients who received early enteral nutrition (<48 h after admission to the intensive care unit) and patients receiving delayed enteral nutrition (initiated >48 h after admission). RESULTS: Enteral nutrition was initiated in 90/142 (63%) patients. Early enteral nutrition was provided in 34/90 (38%) while delayed nutrition occurred in 56/90 (62%). In adjusted analysis including patients who received nutrition, delayed enteral feeding was associated with increased odds of neurologically favorable survival (29 vs 54%, CI 1.04-7.25, p = 0.04). There were no significant differences in the incidence of pneumonia (18 vs 27%, p = 0.16), gastrointestinal bleeding (5.9 vs 3.6%, p = 0.42), intestinal ischemia (5.9 vs 5.4%, p = 0.90), ileus (12 vs 11%, p = 0.98), or need for tracheostomy (15 vs 20%, p = 0.81) between early and late feeding groups. CONCLUSION: In patients with refractory OHCA treated with ECPR and TTM, delayed enteral nutrition was associated with improved neurologically favorable survival. Adverse events related to enteral feeding were not associated with timing of feeding initiation.

BACKGROUND: The objective of this study was to evaluate risk factors, incidence, management, and outcome of endovenous heat-induced thrombosis (EHIT) related to radiofrequency ablation (RFA). METHODS: This was a single-center retrospective analysis of patients over the age of 18 who underwent RFA between 2016 and 2019. Demographics, comorbidities, medications, severity scores, vascular anatomy, procedural details, and outcome data were collected. EHIT-related data included occurrence, grade, laterality, management, and outcome. RESULTS: During the study period, 672 RFA procedures were performed at our institution. Of these, 642 (median age 57 (21-93), 62.3% female) met study inclusion criteria. EHIT was observed in 43 (6.6%) cases. Concurrent left common femoral vein (CFV) or right femoral vein (FV) incompetence was found to be more prevalent in the EHIT group (P = 0.024 and P = 0.011, respectively). Compared with performing RFA alone, concurrent performance of stab phlebectomy and sclerotherapy with RFA on the left side was found to be associated with possible increased risk for EHIT (P = 0.021). Furthermore, patients with diabetes mellitus (DM) (P = 0.05) and those with median diameter of the treated left vein of 1.2 cm (P = 0.02) were more likely to have a higher EHIT grade (III and IV) than those without DM and those with smaller vein diameter, respectively. Management included aspirin (44%), anticoagulant (28%), both (10%), or neither (18%). EHIT either resolved or regressed (64%), did not change (5%), or propagated (8%) at follow-up. CONCLUSIONS: Left CFV or right FV incompetence was found to be more prevalent in the total EHIT group. Furthermore, DM and the median size of the treated vein on the left (1.2 cm) were more prevalent in the high (III-IV) versus low grade (I-II) EHIT group. More than 50% of EHIT improved (regressed or resolved) at follow-up regardless of the management option. Further analysis with larger patient samples are needed to confirm the association between these variables and the development of EHIT.

OBJECTIVES: To investigate the baseline risk of patients treated with Extracorporeal Cardiopulmonary Membrane Oxygenation (ECMO) in relation to cannulation strategy and indication for ECMO as well as the relation of cannulation strategy with survival and secondary hospitalization outcomes. METHODS: Severity of illness and predicted mortality risk were assessed in 317 patients. Central cannulation was used in 52 patients unable to wean off cardiopulmonary bypass after cardiac surgery. Peripheral cannulation was used in 179 patients for extracorporeal cardiopulmonary resuscitation (eCPR) and in 86 patients who received ECMO for refractory cardiogenic shock (RCS). RESULTS: Acute Physiology and Chronic Health Evaluation II (APACHE II) scores were significantly worse (P < 0.01) for peripheral ECMO eCPR (23.2) vs central ECMO (14.6) and vs peripheral ECMO for RCS (18.9). Survival After Venoarterial ECMO (SAVE) scores were significantly worse for peripheral ECMO for eCPR (-7.85) and RCS (-10.38) vs central ECMO (-3.97), and P < 0.01. Peripherally cannulated patients had significantly worse renal function. No significant difference existed for survival to discharge (peripheral ECMO for eCPR, 31%; central ECMO, 44%; peripheral ECMO for refractory cardiac shock, 39.5%; and P = 0.176), although centrally cannulated patients had significantly longer treatment durations compared with peripheral ECMO for eCPR. CONCLUSIONS: Peripherally cannulated patients with eCPR had significantly worse APACHE II and SAVE scores compared to peripherally cannulated RCS or patients with central ECMO, despite having similar mortality.

OBJECTIVE: To assess the prevalence of therapy-related kidney outcomes in survivors of Wilms tumor (WT). STUDY DESIGN: This prospective cohort study included survivors of WT who were ≥5 years old and ≥1 year from completing therapy, excluding those with preexisting hypertension, prior dialysis, or kidney transplant. Participants completed 24-hour ambulatory blood pressure monitoring (ABPM). Abnormal blood pressure (BP) was defined as ≥90th percentile. Masked hypertension was defined as having normal office BP and abnormal ABPM findings. Urine was analyzed for kidney injury molecule-1, interleukin-18, epidermal growth factor, albumin, and creatinine. The estimated glomerular filtration rate (eGFR) was calculated using the bedside chronic kidney disease in children equation. Recent kidney ultrasound examinations and echocardiograms were reviewed for contralateral kidney size and left ventricular hypertrophy, respectively. Clinical follow-up data were collected for approximately 2 years after study enrollment. RESULTS: Thirty-two participants (median age, 13.6 years [IQR, 10.5-16.3 years]; 75% stage 3 or higher WT) were evaluated at a median of 8.7 years (IQR, 6.5-10.8 years) after therapy; 29 participants underwent unilateral radical nephrectomy, 2 bilateral partial nephrectomy, and 1 radical and contralateral partial nephrectomy. In this cohort, 72% received kidney radiotherapy and 75% received doxorubicin. Recent median eGFR was 95.6 mL/min/1.73 m2 (IQR, 84.6-114.0; 11 [34%] had an eGFR of <90 mL/min/1.73 m2). Abnormal ABPM results were found in 22 of 29 participants (76%), masked hypertension in 10 of 29 (34%), and microalbuminuria in 2 of 32 (6%). Of the 32 participants, 22 (69%) had abnormal epidermal growth factor; few had abnormal kidney injury molecule-1 or interleukin-18. Seven participants with previous unilateral nephrectomy lacked compensatory contralateral kidney hypertrophy. None had left ventricular hypertrophy. CONCLUSIONS: In survivors of WT, adverse kidney outcomes were common and should be closely monitored.

BACKGROUND: The mechanisms and degree of myocardial recovery during treatment with venoarterial extracorporeal membrane oxygenation (VA-ECMO) are unclear. We performed a descriptive study to evaluate myocardial recovery and changes in parameters of myocardial loading using echocardiography. METHODS: We retrospectively evaluated patients with refractory ventricular tachycardia/ventricular fibrillation out-of-hospital cardiac arrest who were treated with the Minnesota Resuscitation Consortium protocol. Left ventricular ejection fraction (LVEF), end-diastolic diameter (LVEDD), end-systolic diameter (LVESD), and fractional shortening were assessed using serial echocardiography. One-way analysis of variance (ANOVA) was used to compare parameters over six hospitalization stages. Two-way ANOVA was used to compare these parameters between patients that survived the index hospitalization and those that died. RESULTS: 77 patients had >1 echocardiographic turndown evaluations. Thirty-eight patients survived to discharge and 39 patients died. Of 39 in-hospital deaths, 17 patients died before VA-ECMO decannulation and 22 patients died after VA-ECMO decannulation. Among all patients, LVEF improved from 9.7⯱â¯10.1% from the first echocardiogram after rewarming to 43.1⯱â¯13.1% after decannulation (pâ¯<â¯0.001) and fractional shortening ratio improved from 0.14⯱â¯0.12 to 0.31⯱â¯0.14 (pâ¯<â¯0.001). The LVEDD and LVESD remained stable (pâ¯=â¯0.36 and pâ¯=â¯0.12, respectively). Patients that died had a lower LVEF by an average of 6.93% (95% confidence interval: -10.0 to -3.83, pâ¯<â¯0.001), but other parameters were similar. CONCLUSION: Refractory cardiac arrest patients treated with VA-ECMO experience significant recovery of ventricular function during treatment. We postulate that this primarily occurs via reduction of LV preload.

PURPOSE: While gender-affirming hormones (GAH) may impact the fertility of transgender and gender diverse (TGGD) youth, few pursue fertility preservation (FP). The objective of this study is to understand youth and parent attitudes toward FP decision-making. METHODS: This study is a cross-sectional survey of youth and parents in a pediatric, hospital-based gender clinic from April to December 2017. Surveys were administered electronically, containing 34 items for youth and 31 items for parents regarding desire for biological children, willingness to delay GAH for FP, and factors influencing FP decisions. RESULTS: The mean age of youth (n = 64) was 16.8 years, and 64% assigned female at birth; 46 parents participated. Few youth (20%) and parents (13%) found it important to have biological children or grandchildren, and 3% of youth and 33% of parents would be willing to delay GAH for FP. The most common factor influencing youth FP decision-making was discomfort with a body part they do not identify with (69%), and for the parents, whether it was important to their child (61%). In paired analyses, youth and their parents answered similarly regarding youth desire for biological children and willingness to delay GAH for FP. CONCLUSIONS: The majority of TGGD youth and parents did not find having biological offspring important and were not willing to delay GAH for FP. Discomfort with reproductive anatomy was a major influencing factor for youth FP decision-making and their child's wishes was a major factor for parents. Future qualitative research is needed to understand TGGD youth and parent attitudes toward FP and to develop shared decision-making tools.

PURPOSE: This study sought to evaluate the prevalence of menopausal symptoms in a population of reproductive-aged women remote from cancer therapy compared with a group of healthy similar-aged controls and with a cohort of late reproductive-aged (LR) controls. METHODS: Participants were assessed for symptoms of menopause, early follicular phase hormones, and ultrasound examinations. Menopausal symptoms were analyzed in exposed participants and controls using χ2 analyses, Wilcoxon-Mann Whitney tests, and multivariable logistic regression models. RESULTS: One hundred seventy cancer survivors, 135 similar-aged controls, and 71 LR controls were followed prospectively for an average of 38 months. Compared with similar-aged controls, a greater proportion of survivors reported vasomotor symptoms at some point over the study period (35% vs 19%, p < 0.01), and this proportion was similar to LR controls (44%, p = 0.22). Survivors were more likely to be bothered by vaginal dryness (27%) than similar-aged controls (16%, p = 0.02) or LR controls (14%, p = 0.02). FSH levels were 38.4% higher in those with vasomotor symptoms compared with those without symptoms (p = 0.021). CONCLUSIONS: Reproductive-aged cancer survivors have a higher prevalence of vasomotor symptoms and vaginal dryness than their similar-aged peers. IMPLICATIONS FOR CANCER SURVIVORS: Providers should be attuned to the high prevalence of menopausal symptoms in cancer survivors.

Sodium nitroprusside-enhanced cardiopulmonary resuscitation has shown superior resuscitation rates and neurologic outcomes in large animal models supporting the need for a randomized human clinical trial. This study is the first to show nonselective pulmonary vasodilation as a potential mechanism for the hemodynamic benefits. The pulmonary shunting that is created requires increased oxygen treatment, but the overall improvement in blood flow increases minute oxygen delivery to tissues. In this context, hypoxemia is an important safety endpoint and a 100% oxygen ventilation strategy may be necessary for the first human clinical trial.
ABSTRACT
BACKGROUND: The likelihood of neurologically favorable survival declines with prolonged resuscitation. However, the ability of extracorporeal cardiopulmonary resuscitation (ECPR) to modulate this decline is unknown. Our aim was to examine the effects of resuscitation duration on survival and metabolic profile in patients who undergo ECPR for refractory ventricular fibrillation/ventricular tachycardia out-of-hospital cardiac arrest. METHODS: We retrospectively evaluated survival in 160 consecutive adults with refractory ventricular fibrillation/ventricular tachycardia out-of-hospital cardiac arrest treated with the University of Minnesota (UMN) ECPR protocol (transport with ongoing cardiopulmonary resuscitation [CPR] to the cardiac catheterization laboratory for ECPR) compared with 654 adults who had received standard CPR in the amiodarone arm of the ALPS trial (Amiodarone, Lidocaine, or Placebo Study). We evaluated the metabolic changes and rate of survival in relation to duration of CPR in UMN-ECPR patients. RESULTS: Neurologically favorable survival was significantly higher in UMN-ECPR patients versus ALPS patients (33% versus 23%; P=0.01) overall. The mean duration of CPR was also significantly longer for UMN-ECPR patients versus ALPS patients (60 minutes versus 35 minutes; P<0.001). Analysis of the effect of CPR duration on neurologically favorable survival demonstrated significantly higher neurologically favorable survival for UMN-ECPR patients compared with ALPS patients at each CPR duration interval <60 minutes; however, longer CPR duration was associated with a progressive decline in neurologically favorable survival in both groups. All UMN-ECPR patients with 20 to 29 minutes of CPR (8 of 8) survived with neurologically favorable status compared with 24% (24 of 102) of ALPS patients with the same duration of CPR. There were no neurologically favorable survivors in the ALPS cohort with CPR ≥40 minutes, whereas neurologically favorable survival was 25% (9 of 36) for UMN-ECPR patients with 50 to 59 minutes of CPR and 19% with ≥60 minutes of CPR. Relative risk of mortality or poor neurological function was significantly reduced in UMN-ECPR patients with CPR duration ≥60 minutes. Significant metabolic changes included decline in pH, increased lactic acid and arterial partial pressure of carbon dioxide, and thickened left ventricular wall with prolonged professional CPR. CONCLUSIONS: ECPR was associated with improved neurologically favorable survival at all CPR durations <60 minutes despite severe progressive metabolic derangement. However, CPR duration remains a critical determinate of survival.

INTRODUCTION: Survivors of childhood cancers undergo routine pulmonary function testing as they are at an increased lifetime risk for significant lung disease. However, this population also demonstrates growth abnormalities that could influence the interpretation of these tests, as reference equations are based on standing height. We aim to determine the impact of the relative thoracic growth deficiency in childhood cancer survivors on the interpretation of pulmonary function testing. METHODS: Standing height and upper segment length (USL) in childhood cancer survivors undergoing pulmonary function testing at a single academic center were compared to age-matched historical standards. Additionally, pulmonary function tests were compared to reference values generated from standing height and doubled USL. RESULTS: Data were obtained from 107 cancer survivors. While the subjects demonstrated an overall 6.8% lower standing height vs historical standards, they also demonstrated relative thoracic growth abnormality with a further 9.9% decrement in the ratio USL to standing height. The use of doubled upper segment length as a surrogate measure for standing height in pulmonary function reference equations decreased the number of patients with restrictive lung disease as indicated by spirometry. CONCLUSIONS: Childhood cancer survivors have disproportionately worse thoracic growth deficiency vs appendicular growth deficiency. As a result, their USL is disproportionately short for their standing height, which is most commonly used in pulmonary function testing reference equations. This leads to an increased likelihood in these patients meeting pulmonary function test criteria for restrictive lung disease.

BACKGROUND: Resuscitation of refractory out-of-hospital ventricular fibrillation/ventricular tachycardia (VF/VT) cardiac arrest using extracorporeal membrane oxygenation (ECMO) establishes a complex patient population. We aimed to describe the critical care strategies and outcomes in this population. METHODS: Between December 1, 2015 and January 1, 2018, 100 consecutive adult patients with refractory VF/VT out-of-hospital cardiac arrest and ongoing CPR were transported to the cardiac catheterization laboratory. ECMO, coronary angiography, and percutaneous coronary intervention were performed. Patients achieving an organized cardiac rhythm were admitted to the cardiac intensive care unit (CICU). All patients were considered eligible for necessary intervention/surgery until declaration of death. RESULTS: Of 100 appropriately transported patients, 83 achieved CICU admission. 40/83 (48%) discharged functionally intact. Multi-system organ failure occurred in all patients. Cardiac, pulmonary, renal, and liver injury improved within 3-4 days. Neurologic injury caused death in 26/37 (70%) patients. Poor neurologic outcomes were associated with anoxic injury or cerebral edema on admission head CT, decline in cerebral oximetry over the first 48 h, and elevated neuron specific enolase on CICU admission. For survivors, mean time to ECMO decannulation was 3.5 ± 0.2 days, following commands at 5.7 ± 0.8 days, and hospital discharge at 21 ± 3.2 days. 41/83 (49%) patients developed infections. CPR caused traumatic injury requiring procedural/surgical intervention in 22/83 (27%) patients. CONCLUSIONS: Multi-system organ failure is ubiquitous but treatable with adequate hemodynamic support. Neurologic recovery was prolonged requiring delayed prognostication. Immediate 24/7 availability of surgical and medical specialty expertise was required to achieve 48% functionally intact survival.

PURPOSE: The purpose of this study was to explore the decision-making influences, perceived level of control over decision-making, and mood states of parents and patients who were offered OTC prior to gonadotoxic therapy. METHODS: Parents and patients, at least 12 years old, who required gonadotoxic therapy and were offered OTC prior to therapy, were asked to complete questionnaires. Two validated instruments were also used: the Decision-Making Control Instrument (DMCI) and the Profile of Mood States (POMS). The factors that influenced decision-making were compared using Student's t test, and the scores of DMCI and POMS were compared using the Mann-Whitney test. RESULTS: Thirty-six parents and 16 patients who elected ovarian tissue cryopreservation (OTC) completed questionnaires. Five parents who declined OTC also completed questionnaires. Accepters thought OTC was a good idea and that, in the future, science would enable cryopreserved ovarian tissue to be used to restore fertility (100% parents, 93.8% patients). Among accepters, the desire for genetically related children and prevention of the stress of infertility drove parents' and patients' decisions (90.9 and 100%, respectively). The desire to prevent the stress of infertility was important to parents, but patients were less likely to report that a desire to prevent the stress of infertility factored into their decision-making (66.7 vs. 50.0%; p < 0.001). All respondents felt in control of their decision and displayed low levels of mood disturbance. CONCLUSIONS: Though the decision to undergo experimental OTC is difficult and often urgent, this study suggests that families feel in control of their decision-making and report little emotional disturbance.

BACKGROUND: This study underscores the importance of the survivor/parent dynamic in understanding the knowledge level of childhood cancer survivors and their parents with regard to cancer diagnosis, treatments, and potential late effects, and to assess the impact of parental knowledge on survivor's knowledge. PROCEDURE: A convenience sample (N = 219 dyads) consisting of childhood cancer survivors with a parent match was used. Survivors 2 years out from completion of therapy, aged 16 to 25 years, and fluent in English or Spanish completed 2 questionnaires to assess adolescent and young adult and parental knowledge regarding diagnosis, treatment, and long-term risks. RESULTS: Data from the survivor/parent dyad confirm that parents are more knowledgeable than their child regarding treatment specifics. However, survivors are more accurate when assessing second tumor and fertility risk. More knowledgeable parents led to more knowledgeable survivors. CONCLUSIONS: Although parents were well-informed about treatment specifics, they were not as accurate in identifying risks appropriately. Therefore, education must be directed at both parent and survivors to maximize knowledge.

PURPOSE: Gonadal damage is a common consequence of treatment for pediatric malignancies. Nononcologic conditions may also utilize treatments with potential impact on fertility. Models for oncology fertility preservation programs have emerged and demonstrate that a multidisciplinary team approach can have a positive impact on referral patterns, appropriate risk counseling, and access to fertility preservation options. Expansion of programmatic breadth is needed, providing improved care to nonmalignant conditions where the disease itself may impact reproductive health or treatment modalities. METHODS: With support from the Department of Pediatrics Chair's Initiative, a multidisciplinary, hospital-wide Fertility Preservation Service was created at the Children's Hospital of Philadelphia. A centralized team provides fertility consults across the institution, allowing for risk-based counseling and facilitation of fertility preservation options (both standard care and experimental). RESULTS: Team structure, consult process, and available fertility options for prepubertal and pubertal males and females are described. Preinitiative and postinitiative referral patterns were analyzed. Postinitiative referrals from divisions outside oncology more than doubled (34% vs. 15% at baseline). CONCLUSIONS: A comprehensive model for fertility counseling provides accessible, high-value fertility preservation care to pediatric and young adult patients with a wide variety of diagnoses. A centralized point of contact ensures timely referrals and risk-based counseling and streamlines access to fertility preservation procedures.
