OBJECTIVE: To determine the prevalence of menstrual and reproductive dysfunction among subjects who have undergone radioiodine treatment for thyroid carcinoma.
METHODOLOGY: This study enrolled adult women with Differentiated Thyroid Carcinoma who received the treatment at age 40 years and below. Data was processed using SAS program and evaluated using Fischer's test and Wilcoxon test.
RESULTS: The study enrolled 46 women. Three reported cycle irregularities, 4 reported changes in amount of bleeding and 1 had amenorrhea. The prevalence rate of menstrual abnormalities was 15.2%. These women received a significantly higher dose of radioactive iodine (RAI) (120 vs. 110 mCi, p = 0.0064). Eleven women tried to conceive and there were 5 births to 5 different subjects after radiation. There were no congenital anomalies and 1 miscarriage. Four women were menopausal with an average age of 44.4 years old.
CONCLUSION: This study showed that the prevalence of menstrual disturbances after high dose radioactive iodine treatment among thyroid cancer patients is 15.2%. The affected group received a significantly higher dose of radioactive iodine compared to the unaffected group.

Systematic reviews and meta-analysis combine results and analysis of data from different primary studies (e.g. cross-sectional studies, case-control studies, cohort studies) conducted on similar or related research topics. They are secondary studies that guide clinical decision-making, delivery of care and policy development. This article aims to discuss how to conduct a systematic review and meta-analysis. The steps in conducting a systematic review and meta-analysis include: 1) Identify the purpose including formulating the research question and validating the purpose of the literature scan, 2) Formulate the objectives, 3) Literature search including selection of studies based on population, intervention, comparison and outcome, 4) Retrieval of full text articles, 5) Critical appraisal of articles, 6) Data extraction, 7) Data analysis and 8) Writing the final report. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) is a useful guide in conducting and write systematic review and meta-analysis. While ethics approval is not usually required for systematic review and meta-analysis, authors of such study should still observe good practices including avoiding plagiarism, maintaining transparency and ensuring data accuracy.

Qualitative research is a type of research that provides deeper insights into real-world problems. It gathers participants’ experiences, perceptions, and behaviours and answers the how’s and whys instead of how many or how much. It could be structured as a stand-alone study, purely relying on qualitative data or it could be part of mixed-methods research that combines qualitative and quantitative data. Some of the most common methodologies being used in qualitative research include ethnography, grounded theory, phenomenological study, narrative study, historical study and case studies. This article aimed to discuss how to conduct a qualitative study. The steps in conducting a qualitative study include: 1) Create a purpose statement; 2) Formulate the Research Questions; 3) Perform a Literature Review; 4) Choose a qualitative research methodology to use; 5) Identify and Select the Study Population; 6) Develop the data collection procedure; 7) Collect the data and 8) Analyze the data, which if using thematic analysis, can include writing the final report. In writing and appraising qualitative studies, the Consolidated Criteria for Reporting Qualitative Studies (COREQ) can serve as a useful guide. Lastly, like in quantitative studies, researchers doing qualitative studies should be aware of the ethical issues involved in their work, anticipate possible ethical concerns, craft protection strategies, and make the necessary referrals to research ethics committees, appropriate organizations, and other agencies if the need arises.
