Incidence and risk factors for postpartum mood and anxiety disorders among women veterans.

BACKGROUND: Our aim was to determine rates of postpartum mood and anxiety disorders (PMADs) among U.S. women Veterans and the overlap among PMADs. We further sought to identify PMAD risk factors, including those unique to military service. METHODS: A national sample of women Veterans completed a computer-assisted telephone interview (N = 1414). Eligible participants were aged 20-45 and had separated from service within the last 10 years. Self-report measures included demographics, general health, reproductive health, military exposures, sexual assault, childhood trauma, and posttraumatic stress disorder (PTSD). The PMADs of interest were postpartum depression (PPD), postpartum anxiety (PPA) and postpartum PTSD (PPPTSD). This analysis included 1039 women Veterans who had ever been pregnant and who answered questions about PPMDs related to their most recent pregnancy. RESULTS: A third (340/1039, 32.7%) of participants were diagnosed with at least one PMAD and one-fifth (215/1039, 20.7%) with two or more. Risk factors common for developing a PMAD included: a mental health diagnosis prior to pregnancy, a self-report of ever having had a traumatic birth experience, and most recent pregnancy occurring during military service. Additional risk factors were found for PPD and PPPTSD. CONCLUSION: Women Veterans may be at an increased risk for developing PMADs due to high rates of lifetime sexual assault, mental health disorders, and military-specific factors including giving birth during military service and military combat deployment exposures.

Lifetime infertility and environmental, chemical, and hazardous exposures among female and male US veterans.

BACKGROUND: Veterans experience many potentially hazardous exposures during their service, but little is known about the possible effect of these exposures on reproductive health. OBJECTIVE: This study aimed to assess the association between infertility and environmental, chemical, or hazardous material exposures among US veterans. STUDY DESIGN: This study examined self-reported cross-sectional data from a national sample of female and male US veterans aged 20 to 45 years separated from service for ≤10 years. Data were obtained via a computer-assisted telephone interview lasting an average of 1 hour and 27 minutes that assessed demographics, general and reproductive health, and lifetime and military exposures. Logistic regression models were used to evaluate associations between exposures to environmental, chemical, and hazardous materials and infertility as defined by 2 different definitions: unprotected intercourse for ≥12 months without conception and trying to conceive for ≥12 months without conception. RESULTS: Of the veterans included in this study, 592 of 1194 women (49.6%) and 727 of 1407 men (51.7%) met the unprotected intercourse definition for infertility, and 314 of 781 women (40.2%) and 270 of 775 men (34.8%) met the trying to conceive definition for infertility. Multiple individual exposure rates were found to be higher in women and men veterans with self-reported infertility, including petrochemicals and polychlorinated biphenyls, which were higher in both the men and women groups reporting infertility by either definition. Importantly, there was no queried exposure self-reported at higher rates in the noninfertile groups. Moreover, veterans reporting infertility reported a higher number of total exposures with a mean±standard deviation of 7.61±3.87 exposures for the women with infertility vs 7.13±3.67 for the noninfertile group (P=.030) and 13.17±4.19 for veteran men with infertility vs 12.54±4.10 for the noninfertile group (P=.005) using the unprotected intercourse definition and 7.69±3.79 for the women with infertility vs 7.02±3.57 for the noninfertile group (P=.013) and 13.77±4.17 for the veteran men with infertility vs 12.89±4.08 for the noninfertile group (P=.005) using the trying to conceive definition. CONCLUSION: The data identified an association between infertility and environmental, chemical, and hazardous materials that the veterans were exposed to during military service. Although this study was limited by the self-reported and unblinded data collection from a survey, and causation between exposures and infertility cannot be proven, it does show that veterans encounter many exposures during their service and calls for further research into the possible link between veteran exposures and reproductive health.

Condition, disease, disability: how the label used to describe infertility may affect public support for fertility treatment coverage.

PURPOSE: To assess public attitudes towards fertility treatment coverage and whether attitudes are influenced by infertility labels. METHODS: Cross-sectional, web survey-based experiment using a national sample of 1226 United States adults. Participants read identical descriptions about infertility, with the exception of random assignment to infertility being labeled as a "condition," "disease," or "disability." Participants then responded to questions measuring their beliefs and attitudes towards policies related to the diagnosis and treatment of infertility. We measured public support for infertility policies, public preference for infertility labels, and whether support differed by the randomly assigned label used. We also queried associations between demographic data and support for infertility policies. RESULTS: Support was higher for insurance coverage of infertility treatments (p=.014) and fertility preservation (p=.017), and infertility public assistance programs (p=.036) when infertility was described as a "disease" or "disability" compared to "condition." Participants who were younger, were planning or trying to conceive, had a family member or friend with infertility, and/or had a more liberal political outlook were more likely to support infertility policies. A majority of participants (78%) felt the term "condition" was the best label to describe infertility, followed by "disability" (12%). The least popular label was "disease" (10%). Those preferring "condition" were older (p<.001), more likely to be non-Hispanic White (p=.046), and less likely to have an infertility diagnosis (p<.001). CONCLUSION: While less commonly identified as the best descriptors of infertility, labeling infertility as a "disease" or "disability" may increase support for policies that improve access to infertility care.

Veteran-Reported Receipt of Prepregnancy Care: Data from the Examining Contraceptive Use and Unmet Need (ECUUN) Study.

OBJECTIVES: To identify the prevalence of women Veterans reporting receipt of counseling about health optimization prior to pregnancy, topics most frequently discussed, and factors associated with receipt of this care. METHODS: We analyzed data from a nationally representative, cross-sectional telephone survey of women Veterans (n = 2302) ages 18-45 who used VA for primary care in the previous year. Our sample included women who were (1) currently pregnant or trying to become pregnant, (2) not currently trying but planning for pregnancy in the future, or (3) unsure of pregnancy intention. Multivariable logistic regression was used to examine adjusted associations of patient- and provider-level factors with receipt of any counseling about health optimization prior to pregnancy (prepregnancy counseling) and with counseling on specific topics. RESULTS: Among 512 women who were considering or unsure about pregnancy, fewer than half (49%) reported receiving any prepregnancy counseling from a VA provider in the past year. For those who did, the most frequently discussed topics included healthy weight (29%), medication safety (27%), smoking (27%), and folic acid use before pregnancy (27%). Factors positively associated with receipt of prepregnancy counseling include history of mental health conditions (aOR = 1.96, 95% CI: 1.28, 3.00) and receipt of primary care within a dedicated women's health clinic (aOR = 2.07, 95% CI: 1.35, 3.18), whereas factors negatively associated include far-future and unsure pregnancy intentions (aOR = 0.35, 95% CI: 0.17, 0.71 and aOR = 0.33, 95% CI: 0.16, 0.70, respectively). CONCLUSIONS FOR PRACTICE: Routine assessment of pregnancy preferences in primary care could identify individuals to whom counseling about health optimization prior to pregnancy can be offered to promote patient-centered family planning care.

Patient identified factors influencing decisions to seek fertility care: adaptation of a wellness model.

Objective: To adapt a fertility care wellness model.Background: Despite availability of a range of diagnostic and therapeutic services for infertility, many do not seek care or discontinue care prior to achieving a live birth. Wellness models can inform research on patient decisions to seek and continue fertility care, as many barriers and drivers are represented within the dimensions of wellness.Methods: A mixed-methods online survey was completed by 135 people of reproductive age who experienced infertility in the USA. Outcomes included drivers and barriers to seeking or continuing fertility care. Identified factors were compared by treatment history using chi-square and Fisher's exact tests. Themes and patterns were identified within 174 responses to 6 open-response items through conventional content analysis.Results: Thematic analysis revealed practical (environmental, financial, and physical) and affective (emotional, social and spiritual) dimensions of wellness in decisions to seek care (67%), with affective rationales more prominent in decisions to return for care (78%).Conclusion: Decisions to seek fertility care and return after failed treatment integrate practical and affective rationales from financial, physical, environmental, emotional, social and spiritual wellness dimensions. Drivers and barriers within these dimensions should be considered to encourage care seeking and improve patient retention.

Current evidence supporting a goal of singletons: a review of maternal and perinatal outcomes associated with twin versus singleton pregnancies after in vitro fertilization and intracytoplasmic sperm injection.

With increasing use of in vitro fertilization and intracytoplasmic sperm injection (IVF-ICSI) almost 2% of all babies born in the United States each year are now conceived with these technologies, making outcomes of IVF-ICSI extremely important not only to patients and families but to public health. Twin pregnancy rates after IVF-ICSI in the United States have declined since their peak in 2013 but remain at approximately 1 in 10 to 1 in 20 pregnancies. A review of the current international literature on twin versus singleton pregnancy outcomes after IVF-ICSI treatment confirms statistically significantly higher risks to maternal and perinatal health and statistically significantly higher health care costs. The field of infertility care should continue to work to develop practices that lower twin pregnancy rates to an absolute minimum to maximize the safety of these medical treatments.

Infertility and Health-Related Quality of Life in United States Women Veterans.

Background: To assess associations between infertility and health-related quality of life and medical comorbidities in U.S. women Veterans. Materials and Methods: This cross-sectional observational study involved computer-assisted telephone interviews of Veterans Administration-enrolled women between ages 21 and 52 years. Patients were analyzed in two groups by self-reported history of infertility. Outcomes included health-related quality of life as measured by the short-form 12-item interview (SF-12) physical and mental component summary (PCS and MCS) scores, depression, post-traumatic stress disorder (PTSD), eating disorders, fibromyalgia, other chronic pain, cardiovascular disease risk factors, and cancer. Age-adjusted p-values and adjusted odds ratios (AORs) were calculated using individual multivariate regression models to control for significant confounding covariates. Results: Of the 996 women veterans included, 179 (18.0%) reported a history of infertility. Infertility was associated with worse perceived physical health as determined by the SF-12 PCS [beta coefficient (B) -3.23 (-5.18 to -1.28)] and fibromyalgia [AOR 1.97 (1.22 to 3.19)]. Infertility was also associated with higher rates of depression, other chronic pain, and cancer, which remained significant after adjusting for age (p = 0.021, p = 0.016, and p = 0.045, respectively); however, no association for all was seen after adjustment for other significant covariates. There was no difference in Veterans' mental health using the SF-12 MCS, nor differences seen in PTSD or eating disorder rates, or in cardiovascular risk factors. Conclusions: This novel investigation in U.S. women Veterans found worse physical health-related quality of life and increased rates of fibromyalgia among women reporting a history of infertility, adding to the growing literature on infertility as a marker for overall poorer health.

Factors Impacting Fertility Preservation in Adolescents and Young Adults with Cancer: A Retrospective Study.

Purpose: Fertility preservation before therapy is underutilized for those diagnosed with cancer as an adolescent or young adult (AYA). The purpose of this study was to describe factors impacting utilization of fertility preservation consultations and procedures among AYAs at the University of Iowa Health Care (UIHC). Methods: Patients were identified by the oncology registry at UIHC. Disease site, histology, date of diagnosis, sex, race, ethnicity, insurance, and zip code data were gathered by the registrars. UIHC's electronic medical record was queried for fertility preservation consultation. The Reproductive Endocrinology and Infertility clinical database captured information about patients who underwent fertility preservation. Rural-urban commuting area codes measured rurality. Descriptive statistics and multivariate linear probability models were used to predict the probability of fertility preservation consultation and procedure. Results: From 2008 to 2017, 2932 AYAs were treated for an invasive malignancy at UIHC. Of the 440 (15%) who received a fertility preservation consultation, 156 (5%) underwent a fertility preservation procedure. Multivariate analyses showed that AYAs with public insurance coverage, those diagnosed with central nervous system (CNS) disease or melanoma, and those >30 years old at diagnosis had a significant decrease in the percentage point probability of having a consultation. The percentage point probability of undergoing a procedure was decreased for female patients, those with melanoma or carcinoma, those seen by a pediatric-based provider, and those diagnosed after 25 years of age. Conclusion: This study has important implications for practice and policy, particularly regarding insurance coverage and patient and provider characteristics leading to fertility preservation consultations and procedures for AYAs with cancer.

Infertility Services for Veterans: Policies, Challenges, and Opportunities.

Infertility prevalence and care needs among male and female Veterans are understudied topics. The Veterans Health Administration (VHA) medical benefits package covers full infertility evaluation and many infertility treatments for Veterans but not, by law, for their spouses. In vitro fertilization (IVF) is also specifically excluded from this medical benefits package by regulation. Congress passed a law in 2016 that allowed VHA to provide IVF to Veterans and their legal spouses, and broader infertility benefits to the legal spouse, if the Veteran has a service-connected condition associated with his or her infertility, with some limitations. As the Veteran population becomes increasingly female, research efforts in reproductive health, including infertility, are expanding and evolving. This includes a nationwide study currently underway examining infertility among male and female Veterans and associations with military-related trauma, such as injury, posttraumatic stress disorder, military sexual trauma, and toxin exposure. In this review, we describe the state of the science and policy on infertility care in the VHA along with challenges and opportunities that exist within the VHA system.

Ethnic Minority Status and Experiences of Infertility in Female Veterans.

BACKGROUND: In the general population, infertility is increasingly prevalent in ethnic minority women; these women suffer longer and are less likely to access care. There is a paucity of data regarding the issue of race and infertility in the growing female military veteran population. MATERIALS AND METHODS: This cross-sectional observational study involved computer-assisted telephone interviews of 1,004 Veterans Administration (VA)-enrolled women aged ≤52 years. RESULTS: Racial minority veterans were more likely than white veterans to self-report infertility (24% vs. 18%), equally likely to report infertility evaluation (52% vs. 52%), and less likely to report receiving infertility treatment (31% vs. 63%). Differences in self-reported infertility (odds ratios [OR]: 1.50, 95% confidence interval [CI]: 1.02-2.22) and infertility treatment (OR: 0.32, 95% CI: 0.13-0.81) were retained after controlling for age, income, marital status, education, insurance, history of pelvic inflammatory disease, and lifetime sexual assault. While racial minority veterans were equally as likely as white veterans to be evaluated for infertility, white and racial minority groups reported different reasons for not seeking evaluation. CONCLUSIONS: Consistent with civilian studies, our data suggest that racial minority VA-enrolled female veterans are more likely to self-report infertility and less likely to receive infertility treatment. Future research should investigate whether these findings are consistent nationwide and regardless of VA enrollment, and if minority veterans have unique barriers to care. A better understanding of how the VA might improve awareness of infertility evaluation and treatment options, especially for racial minority veterans, is needed.

Müllerian Aplasia with Severe Hematometra: A Case Report of Diagnosis and Management in a Low Resource Setting.

BACKGROUND: Müllerian aplasia or Mayer-Rokitansky-Küster-Hauser syndrome is described as congenital absence of the proximal vagina with or without absence of the cervix and uterus, most often recognized after the onset of primary amenorrhea. CASE: An 18-year-old woman presented to a free medical clinic in Arcahaie, Haiti with primary amenorrhea, abdominal distention, and cyclic monthly abdominal pain. Physical exam was significant for uterus palpable superior to the umbilicus, absence of vagina, and rectal exam without palpable vagina or cervix. Transabdominal and transperineal ultrasound examinations did not reveal hematocolpos. Exploratory laparotomy revealed severe endometriosis with bilateral hematosalpinx, markedly distended uterus, no proximal vagina, and normal ovaries. Uterine specimen was filled with blood and no clear cervix was present. SUMMARY AND CONCLUSION: Diagnosis of vaginal and cervical agenesis is complicated in low-resource settings and treatment must be modified when subspecialty care and consistent follow-up are not available.

Preconception Care in the Veterans Health Administration.

Preconception care (PCC), defined as a set of interventions to help women optimize their health and well-being prior to pregnancy, can improve pregnancy outcomes and is recommended by national organizations including the Centers for Disease Control and Prevention and the American College of Obstetricians and Gynecologists. Women Veterans who use the Department of Veterans Affairs (VA) health care system may face elevated risks of adverse pregnancy and birth outcomes due to a high prevalence of chronic medical and mental health conditions as well as psychosocial stressors including sexual trauma history and intimate partner violence. Many women Veterans of childbearing age experience poverty and homelessness, which are key social determinants of poor reproductive health outcomes. Furthermore, racial/ethnic disparities in maternal and neonatal outcomes are well documented, and nearly half of women Veterans of reproductive age are minority race/ethnicity. High-quality, equitable, patient-centered PCC services to address modifiable risks in this population are therefore a priority for VA. In this article, we provide a brief background of PCC, discuss the health risks of Veterans associated with adverse pregnancy outcomes, and highlight VA initiatives related to PCC. Lastly, we discuss implications and future directions for PCC research and policy within VA and across other health systems.

Difference between mean gestational sac diameter and crown-rump length as a marker of first-trimester pregnancy loss after in vitro fertilization.

OBJECTIVE: To investigate whether the difference between mean gestational sac diameter and crown-rump length (mGSD - CRL) is associated with first-trimester pregnancy loss or adverse pregnancy outcomes after in vitro fertilization (IVF) and to determine if mGSD - CRL is a better predictor of pregnancy loss than either measurement alone. DESIGN: Retrospective cohort study. SETTING: University hospital. PATIENT(S): A total of 1,243 IVF cycles with fresh or cryopreserved autologous embryo transfers resulting in singleton gestations performed at the University of Iowa Hospitals and Clinics from January 2005 through December 2014. Cycles included ultrasound measurements of mGSD and CRL at 45-56 days' gestation. INTERVENTION(S): Mean gestational sac diameter to crown-rump length difference. MAIN OUTCOME MEASURE(S): Primary outcomes were first-trimester pregnancy loss and gestational age at delivery. Secondary outcomes were infant birth weight and pregnancy complications. RESULT(S): First-trimester pregnancy loss rates were significantly higher in pregnancies with mGSD - CRL <5 mm (43.7%) compared with 5-9.99 mm (15.8%), 10-14.99 mm (9.9%), and ≥15 mm (7.1%). No correlations were found with infant birth weight, gestational age at delivery, or other pregnancy complications. mGSD - CRL was not a better predictor of pregnancy loss than mGSD or CRL alone. CONCLUSION(S): There is a strong inverse relationship between mGSD - CRL and first-trimester pregnancy loss in IVF patients, although the incidence of pregnancy loss with a mGSD - CRL <5 mm was significantly lower than previously reported. Small mGSD - CRL was not associated with an increased risk of complications in pregnancies that continued beyond 20 weeks. The association between mGSD, CRL, and miscarriage is complex.

Fertility preservation training for obstetrics and gynecology fellows: a highly desired but non-standardized experience.

BACKGROUND: Despite a large body of data suggesting that delivery of fertility care to cancer patients is inconsistent and frequently insufficient, there is a paucity of literature examining training in fertility preservation for those physicians expected to discuss options or execute therapy. The study objective was to compare fertility preservation training between Reproductive Endocrinology & Infertility (REI) and Gynecologic Oncology (GYN ONC) fellows and assess the need for additional education in this field. METHODS: A 38-item survey was administered to REI and GYN ONC fellows in the United states in April 2014. Survey items included: 1) Clinical exposure, perceived quality of training, and self-reported knowledge in fertility preservation; 2) an educational needs assessment of desire for additional training in fertility preservation. RESULTS: Seventy-nine responses were received from 137 REI and 160 GYN ONC fellows (response rate 27%). REI fellows reported seeing significantly more fertility preservation patients and rated their training more favorably than GYN ONC fellows (48% of REI fellows versus 7% of GYN ONC fellows rated training as 'excellent', p < 0.001). A majority of all fellows felt discussing fertility preservation was 'very important' but fellows differed in self-reported ability to counsel patients, with 43% of REI fellows and only 4% of GYN ONC fellows able to counsel patients 'all the time' (p = 0.002). Seventy-six percent of all fellows felt more education in fertility preservation was required, and 91% felt it should be a required component of fellowship training. CONCLUSION: Significant variability exists in fertility preservation training for REI and GYN ONC fellows, with the greatest gap seen for GYN ONC fellows, both in perceived quality of fertility preservation training and number of fertility preservation patients seen. A majority of fellows in both disciplines support the idea of a standardized multi-disciplinary curriculum in fertility preservation.

Hysterectomy risk in premenopausal-aged military veterans: associations with sexual assault and gynecologic symptoms.

BACKGROUND: Several gynecological conditions associated with hysterectomy, including abnormal bleeding and pelvic pain, have been observed at increased rates in women who have experienced sexual assault. Previous findings have suggested that one of the unique health care needs for female military veterans may be an increased prevalence of hysterectomy and that this increase may partially be due to their higher risk of sexual assault history and posttraumatic stress disorder (PTSD). Although associations between trauma, PTSD, and gynecological symptoms have been identified, little work has been done to date to directly examine the relationship between sexual assault, PTSD, and hysterectomy within the rapidly growing female veteran population. OBJECTIVES: The objective of the study was to assess the prevalence of hysterectomy in premenopausal-aged female veterans, compare with general population prevalence, and examine associations between hysterectomy and sexual assault, PTSD, and gynecological symptoms in this veteran population. STUDY DESIGN: We performed a computer-assisted telephone interview between July 2005 and August 2008 of 1004 female Veterans Affairs (VA)-enrolled veterans ≤ 52 years old from 2 Midwestern US Veterans Affairs medical centers and associated community-based outreach clinics. Within the veteran study population, associations between hysterectomy and sexual assault, PTSD, and gynecological symptoms were assessed with bivariate analyses using χ(2), Wilcoxon-Mann-Whitney, and Student t tests; multivariate logistic regression analyses were used to look for independent associations. Hysterectomy prevalence and ages were compared with large civilian populations represented in the Behavioral Risk Factor Surveillance System and American College of Surgeons National Surgical Quality Improvement Program databases from similar timeframes using χ(2) and Student t tests. RESULTS: Prevalence of hysterectomy was significantly higher (16.8% vs 13.3%, P = .0002), and mean age at hysterectomy was significantly lower (35 vs 43 years old, P < .0001) in this VA-enrolled sample of female veterans compared with civilian population-based data sets. Sixty-two percent of subjects had experienced attempted or completed sexual assault in their lifetimes. A history of completed lifetime sexual assault with vaginal penetration (LSA-V) was a significant risk factor for hysterectomy (age-adjusted odds ratio, 1.85), with those experiencing their first LSA-V in childhood or in military at particular risk. A history of PTSD was also associated with hysterectomy (age-adjusted odds ratio, 1.83), even when controlling for LSA-V. These associations were no longer significant when controlling for the increased rates of gynecological pain, abnormal gynecological bleeding, and pelvic inflammatory disease seen in those veterans with a history of LSA-V. CONCLUSION: Premenopausal-aged veterans may be at higher overall risk for hysterectomy, and for hysterectomy at younger ages, than their civilian counterparts. Veterans who have experienced completed sexual assault with vaginal penetration in childhood or in military and those with a history of PTSD may be at particularly high risk for hysterectomy, potentially related to their higher risk of gynecological symptoms. If confirmed in future studies, these findings have important implications for women's health care providers and policy makers within both the VA and civilian health care systems related to primary and secondary prevention, costs, and the potential for increased chronic disease and mortality.

Ethical issues identified by obstetrics and gynecology learners through a novel ethics curriculum.

OBJECTIVE: Obstetrics and gynecology (ob/gyn) is fraught with bioethical issues, the professional significance of which may vary based on clinical experience. Our objective was to utilize our novel ethics curriculum to identify ethics and professionalism issues highlighted by ob/gyn learners and to compare responses between learner levels to further inform curricular development. STUDY DESIGN: We introduced an integrated and dynamic ob/gyn ethics and professionalism curriculum and mixed methods analysis of 181 resulting written reflections (case observation and assessments) from third-year medical students and from first- to fourth-year ob/gyn residents. Content was compared by learner level using basic thematic analysis and summary statistics. RESULTS: Within the 7 major ethics and professionalism domains, learners wrote most frequently about miscellaneous ob/gyn issues such as periviability and abortion (22% of students, 20% of residents) and problematic treatment decisions (20% of students, 19% of residents) rather than professional duty, communication, justice, student-/resident-specific issues, or quality of care. The most commonly discussed ob/gyn area by both learner groups was obstetrics rather than gynecology, gynecologic oncology, or reproductive endocrinology and infertility, although residents were more likely to discuss obstetrics-related concerns than students (65% vs 48%; P = .04) and students wrote about gynecologic oncology-related concerns more frequently than residents (25% vs 6%; P = .002). In their reflections, sources of ethical value (eg, the 4 classic ethics principles, professional guidelines, and consequentialism) were cited more frequently and in greater number by students than by residents (82% of students cited at least 1 source of ethical value vs 65% of residents; P = .01). Residents disagreed more frequently with the ethical propriety of clinical management than did students (67% vs 43%; P = .005). CONCLUSION: Our study introduces an innovative and dynamic approach to an ob/gyn ethics and professionalism curriculum that highlights important learner-identified ethics and professionalism issues both specific to ob/gyn and common to clinical medicine. Findings will help ob/gyn educators best utilize and refine this flexible curriculum such that it is appropriately focused on topics relevant to each learner level.
