RESUMEN
This study investigated the knowledge, thoughts, and attitudes of oncology nurses in China regarding fertility preservation for male cancer patients of childbearing age, and for offering counseling or oncofertility services for the men in their care. Data was collected from 18 oncology nurses in Southwest China through voluntary self-report and in-depth interviews. The qualitative interview data were analyzed using a descriptive phenomenology method based on the lived experience of the nurses. The interviewees commonly reported 6 main concerns regarding fertility preservation (FP): their insufficient knowledge and inadequate nursing education; the importance of offering such services to cancer patients; legal vulnerability if FP information is withheld from patients; the role of the nurse in counseling; and barriers to discussing FP in practice. Nurses had a positive attitude toward FP, but most had no practical role in routinely informing male patients of their options, and the nurses believed that discussion of FP was outside their scope of practice. This study offers insight into the perceptions of oncology nurses in a developing country regarding the provision of FP services for adult male cancer patients. These results lead us to recommend that local fertility nurses should be given new training regarding FP. Furthermore, nurse-led clinics are desirable. Future research should focus on the effectiveness of nurse participation in FP counseling and referral, and how to improve the professional confidence of oncology nurses for addressing FP issues.

The application of straw biochar in farmland in Dongting Lake area can realize the resource utilization of straw and reduce environmental risk. In 2020, a rice pot experiment was conducted to investigate the effects of different biochar application levels on ammonia volatilization rate, cumulative ammonia volatilization, pH value, and NH4+-N concentration in surface water. Six levels of reed (Miscanthus lutarioriparius) biochar amount, i.e., 0%, 1%, 2%, 4%, 6% and 8% of soil weight of the 0-20 cm column, were applied in two typical paddy soils in sou-thern China, i.e., reddish clayey soil derived from quaternary red soil and granitic sandy soil derived from granite. Compound fertilizer was applied at a rate of 200 kg N·hm-2. The results showed that biochar application resulted in significant differences in the rate and cumulative amount of ammonia volatilization between the two soils and among different biochar treatments. For the granitic sandy soil, peak ammonia volatilization under different biochar treatments appeared at the second day after fertilization, which was decreased by 23.6%-53.4%. For the reddish clayey soil, peak ammonia volatilization appeared between the 7th to 13th day after fertilization, which increased with biochar addition level. The rate of ammonia volatilization from the granitic sandy soil was generally higher than that from the reddish clayey soil. For the granitic sandy soil, addition of <4% biochar could inhibit the ammonia volatilization and cumulative volatilization amount, with the greatest reduction (46.9%) at the treatment with 2% biochar addition. The addition of biochar did not affect the pH value of surface water at the early stage of rice growth. For the reddish clayey soil, the pH value and NH4+-N concentration in the surface water increased with biochar addition level, resulting in the increases of ammonia volatilization rate and cumulative volatilization amount by 1.3-10.5 times. Biochar addition level was the key factor affecting ammonia volatilization from the two soils. Elovich equation could well fit the variation trend of cumulative ammonia volatilization with time for the two soils, with the correlation reaching extremely significant level for each treatment. Overall, the application of reed biochar could suppress ammonia volatilization from the granitic sandy soil which was nearly neutral in acidity, while would promote ammonia volatilization via increasing pH value and NH4+-N concentration of surface water for the acidic reddish clayey soil. Therefore, appropriate dosages of reed biochar should be selected for different types of soil in order to reduce nitrogen loss.

The emerging discipline of oncofertility advocates for the timely provision of fertility preservation (FP) to all cancer patients of childbearing age by healthcare providers. A lack of practice due to limited FP-related knowledge was found among healthcare providers. A systematic review was undertaken on the educational programs on FP for healthcare providers. An initial search was performed in MEDLINE, PsycINFO, CINAHL, Web of Science, PubMed, and Scopus databases in October 2019. This review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Among the 160 articles that were identified, five relevant articles published between 2009 and 2019 were reviewed. Of the five studies, three were quantitative nonrandomized studies, one was a randomized controlled trial, and one was a qualitative study. Three programs were relevant to oncology nurses, one was relevant to social workers as well as nurses, and one was relevant to oncology fellows and residents. The four programs significantly increased healthcare providers' knowledge about FP, but clinical practice was only improved in the Educating Nurses about Reproductive Issues in Cancer Healthcare program (P < 0.01). Nevertheless, most of the studies used a self-made questionnaire or tool to assess the effects of the training programs. The educational programs improved the FP-related knowledge of healthcare providers but lacked the high-quality randomized controlled trials needed to provide robust evidence on the effectiveness of training programs using standard tools. More training projects should be developed based on learning theories or models to improve oncofertility care in clinical practice.
