RESUMEN

BACKGROUND: Endocrine measures of ovarian reserve before breast cancer treatment may predict postchemotherapy ovarian function, providing prognostic information at the time of cancer diagnosis. The objectives of this study were 1) to determine whether prechemotherapy levels of antimullerian hormone (AMH), follicle-stimulating hormone (FSH), and inhibin B (inhB) are associated with the return of ovarian function after chemotherapy and 2) to generate a prognostic score for ovarian recovery in young women with breast cancer. METHODS: A prospective cohort study recruited 109 participants (median age, 39 years; age range, 23-45 years) before chemotherapy from 2 breast clinics and followed them longitudinally. By using time-to-event analysis, the authors tested the association between prechemotherapy AMH, FSH, and inhB levels and the time to return of ovarian function, as measured by menstrual pattern. RESULTS: After a median follow-up of 163 days (range, 4-1009 days) after chemotherapy, 62 participants (57%) experienced return of ovarian function. In adjusted analyses, AMH levels >0.7 ng/mL (hazard ratio, 2.9; 95% confidence interval, 1.5-5.6) and FSH levels ≤10 IU/L (hazard ratio, 4.7; 95% confidence interval, 1.3-16.8) were associated with a shorter time to ovarian recovery, whereas inhB levels were not related. A prognostic score based on age <40 years, AMH >0.7 ng/mL, and body mass index ≥25 kg/m(2) was used to estimate the timing of recovery. CONCLUSIONS: In reproductive-aged women with newly diagnosed breast cancer, prechemotherapy AMH and FSH levels were associated with the return of ovarian function, independent of age. A novel prognostic score incorporating AMH, age, and body size was capable of estimating the time to ovarian recovery. Pending validation, these data support using prechemotherapy ovarian reserve measures, particularly AMH, to prospectively counsel young patients on future ovarian function. Because ovarian function is not equivalent to fertility, follow-up studies on predicting fertility are needed.

RESUMEN

OBJECTIVE: To explore the effects of histidine kinase gene CHK1 on some biological characteristics of Candida albicans. METHODS: The effects of gene mutation strains of Candida albicans such as CHK21, CHK25, CHK26 and CHK27 were observed on its reproductive ability, formation of chlamydospore and germ tube and tolerance of Congo red. RESULTS: The reproductive ability in CHK gene mutation strains CHK25, CHK26, CHK27, CHK21 was weaker than that of wild strains(6 h:1.36 ± 0.86,1.25 ± 0.84,1.05 ± 0.79,0.90 ± 0.74 vs 1.54 ± 0.89,P = 0.000).And CHK21 was the most obvious. The formation of germ tube in CHK gene mutation strains CHK21, CHK25, CHK26 and CHK27 was weaker than that of wild strains (2 h: 5.6% ± 2.0%,19.5% ± 6.9%,13.6% ± 4.8% vs 29.6% ± 10.5%,P = 0.023, 0.028, 0.029).Under no light, the mean number of chlamydospore in wild and CHK26 strains was 3 and 22 respectively. With light, the mean number was changed to 60 and 80. So the formation ability of chlamydospore in CHK26 was stronger than other strains. CHK21 could not produce chlamydospore under no light. The mutation strain of CHK1 was sensitive to Congo red. CONCLUSION: CHK1 affect the reproduction and formation of chlamydospore and hypha and the tolerance to some environmental pressures of Candida albicans.

RESUMEN

Purpose: Sexual minority (SM) individuals experience higher rates of anxiety and depression. Previous research on mental health disparities for SM cancer survivors has largely focused on adult survivors; however, studies are limited in the adolescent and young adult (AYA) population. This study's objective is to compare depression and anxiety symptoms between AYA, female cancer survivors who identify as an SM and those who identify as heterosexual. Methods: A cross-sectional analysis of 1025 AYA survivors aged 18-40 years (2015-2017) was performed. Patients self-reported SM identification and depression and anxiety symptoms, as measured by the Patient Health Questionnaire (PHQ8) and Generalized Anxiety Disorder Scale (GAD7), respectively. Multivariable logistic regression tested associations between SM identification and depression and anxiety. Results: Sixty-four participants (6%) identified as an SM. In adjusted analyses, SM participants had 1.88 higher odds of anxiety (odds ratio [OR] 1.88, confidence interval [95% CI] 1.05-3.35, p = 0.033) compared with heterosexual participants. SM participants did not have significantly higher odds of depression (OR 1.36, CI 0.75-2.47, p = 0.31). More social support was significantly associated with lower odds of depression (OR 0.91, CI 0.89-0.93, p < 0.001) and anxiety (OR 0.93, CI 0.91-0.94, p < 0.001). Conclusions: AYA cancer survivors identifying as an SM had nearly twice the odds of anxiety, with social support that is protective for both anxiety and depression. While mental health screening is recommended throughout the cancer care continuum, these data support the need for reliable screening, clinician awareness of increased vulnerability in the AYA, SM survivor population, and clinician training on culturally competent care and generation of evidence-based interventions.

RESUMEN

Purpose: Oncofertility care at cancer diagnosis remains underimplemented across oncology and fertility care settings, with limited tools to scale up effective implementation strategies. Using implementation science theory, we systematically assessed factors that influence oncofertility care implementation and mapped scalable strategies, particularly electronic health record (EHR)-enabled ones, that fit adult and pediatric oncology care contexts. Methods: Using purposeful sampling, we recruited health care providers and female, reproductive-aged survivors of adolescent and young adult (AYA) cancers (AYA survivors) from a comprehensive cancer center and a freestanding children's hospital to semistructured interviews and focus groups. Using thematic analysis combining inductive codes with deductive codes using the Consolidated Framework for Implementation Research (CFIR), we characterized barriers and facilitators to care and designed responsive strategies. Two coders independently coded each transcript. Results: We recruited 19 oncology and fertility providers and 9 cancer survivors. We identified barriers and facilitators to oncofertility care in the CFIR domains of individual, inner setting, outer setting, and process, allowing us to conceptualize oncofertility care to encompass three core components (screening, referral, and fertility preservation counseling) and map five strategies to these components that fit an adult and a children's context and bridge oncology and fertility practices. The strategies were screening using a best practice advisory, referral order, telehealth fertility counseling, provider audit and feedback, and provider education. All but provider education were EHR tools with embedded efficiencies. Conclusion: An implementation science approach systematically assessed oncofertility care and mapped strategies to provide a theory-based approach and scalable EHR tools to support wider dissemination.

RESUMEN

OBJECTIVE: Because hot flashes are a common symptom experienced by women with breast cancer, we sought to explore genetic predictors associated with response to acupuncture for the treatment of hot flashes. METHODS: Using data from our completed randomized controlled trial (Clinicaltrials.gov identifier: NCT01005108) on hot flashes among breast cancer survivors who provided biomarker collection (N = 108), we extracted and assayed DNA for single nucleotide polymorphisms in genes involved in neurotransmission, thermoregulation, and inflammation (ADORA1, COMT, TCL1A, and TRPV1). For our primary outcome we classified individuals with a 50% or more reduction in their hot flash composite score at the end of treatment as responders. We used Fisher exact test to identify individual and combined single nucleotide polymorphisms associated with treatment response. RESULTS: Among women (N = 57) who received acupuncture treatment (electro or sham), we found that women who were carriers of at least one of these six genotypes (ADORA1 rs41264025-GA or rs16851029-GG or rs12744240-GT, COMT rs6269-GA, TCL1A rs2369049-GG, and TRPV1 rs8065080-TT) were more likely to respond to acupuncture for hot flashes than noncarriers (70.3% vs 37.5%, P = 0.035). These six genotypes were not associated with response in women (N = 51) who received pharmacological hot flash treatment (gabapentin or placebo pill; 37.5% vs 37.5%, P = 1.0). CONCLUSIONS: In this exploratory, proof of concept study, we identified six genotypes that may predict response to acupuncture for hot flashes in breast cancer survivors. If confirmed by future studies, these findings may inform the development of personalized acupuncture for managing hot flashes.
