Non-alcoholic fatty liver disease(NAFLD) is a chronic metabolic condition with rapidly increasing incidence, becoming a public health issue of worldwide concern. Studies have shown that farnesoid X receptor(FXR)-based modulation of downstream targets can improve liver function and metabolic status in the patients with NAFLD and may be a potential drug target for treating this di-sease. Great progress has been achieved in the development of drugs targeting FXR for the treatment of NAFLD. A number of studies have explored the traditional Chinese medicine and their active ingredients for the treatment of NAFLD via FXR considering the high safety and efficacy and mild side effects. This paper systematically describes the mechanism of traditional Chinese medicines in the treatment of NAFLD via FXR and the downstream targets, aiming to provide precise targets for the drug development and clinical treatment of NAFLD.

Most differentiated thyroid cancer (DTC) patients have an excellent prognosis. However, about one-third of DTC patients with recurrent or metastatic disease lose the hallmark of specific iodine uptake initially or gradually and acquire radioactive iodine-refractory DTC (RAIR-DTC) with poor prognosis. Due to the potentially severe complications from unnecessarily repeated RAI therapy and encouraging progress of multiple targeted drugs for advanced RAIR-DTC patients, it has become crucial to identify RAIR-DTC early. In this review, we focus on the progress and controversies regarding the defining of RAIR-DTC, further with subsistent approaches and promising molecular nuclear medicine imaging in identifying RAIR-DTC, which may shed light on the proper management methodsof such patients.

PURPOSE: There is substantial need for optimizing radiation protection in nuclear medicine imaging studies. However, the diagnostic reference levels (DRLs) have not yet been established for nuclear medicine imaging studies in Korea.MATERIALS AND METHODS: The data of administered activity in 32 nuclear medicine imaging studies were collected from the Korean Society of Nuclear Medicine (KSNM) dose survey database from 2013 and 2014. Through the expert discussions and statistical analyses, the 75th quartile value (Q3) was suggested as the preliminary DRL values. Preliminary DRLs were subjected to approval process by the KSNM Board of Directors and KSNM Council, followed by clinical applications and performance rating by domestic institutes.RESULTS: DRLs were determined through 32 nuclear medicine imaging studies. The Q3 value was considered as appropriate selection as it was generally consistent with the most commonly administered activity. In the present study, the final version of initial DRL values for nuclear medicine imaging in Korean adults is described including various protocols of the brain and myocardial perfusion imaging.CONCLUSION: The first DRLs for nuclear medicine imaging in Korean adults were confirmed. The DRLs will enable optimized radiation protection in the field of nuclear medicine imaging in Korea.

Nuclear medicine has been offering diagnostic and therapeutic solution since the introduction of radioactive iodine for thyroid diseases since decades. However, the concept of theranostics has given a new found impetus to the use of pairs of radiopharmaceuticals for diagnosis and treatment. Presented here is a perspective on theranostics from Pakistan.

Targeted radionuclide therapy (TRT) is unique because of its efficacy and its theranostic feature in the era of precision medicine. So far, introduction of new TRT has not been going well in Japan due to several reasons including strict regulations, shortage of facilities for TRT, and insufficient reimbursement for TRT in clinic. Japanese community had several strategies to develop TRT in these 10 years, including the establishment of the National Conference for Nuclear Medicine Theranostics in which physicians, scientists, patients, people supporting patients, and industrial people gather. To promote TRTwith supports from the government, the preparatory committee for the establishment of Japan Foundation of Medical Isotope Development (JAFMID) was launched. I would like to call TRT “Precision Nuclear Medicine.” When we can add genomic information here, we can put it to new stage of cancer therapy. It is time for us.

Nuclear medicine in Indonesia has a quite long history since the late 1960s. There are some problems and obstacles that have to be solved and overcome in order to develop nuclear medicine services, spread the services to reach every target area, and implement new novel therapeutic nuclear medicine as well. The right strategy and strong effort should be performed for a successful result. Theranostics nuclear medicine will play a more prominent role in the management of cancer patients.

Medical managements are becoming personalized while diseases are being understood at the molecular level. Nuclear medicine is one of the fields actively contributing to this development. In particular, theranostics, a combinatorial term for therapy and diagnostics, enables accurate imaging and subsequent targeted radionuclide treatment. Due to its high impact in healthcare, many countries have begun to offer Ga-68 PET/CTscans and Lu-177 therapies. The Philippines has followed suit through the initiative of this author and able support of the administration and staff of St. Luke's Medical Center. The Ga-68 DOTATATE and PSMA PET/CT scans became officially available in January 2018 while the first peptide receptor radionuclide therapy for neuroendocrine tumor and first PSMA radioligand therapy for prostate cancer occurred in May and June 2018, respectively. Amidst past, present, and future challenges, theranostics has emerged in the Philippines, offering hope to cancer patients in the country.

Nuclear theranostics functions as a bridge which connects targeted diagnosis to targeted therapy, just like Turkey functions as a geographical bridge which connects Asia to Europe. This unique geographical site of the country plays an important role with regard to introduction of novel scientific and technologic improvements, which originate from one continent to another, in the era of accelerated information. The first nuclear medicine practice in Turkey started in the beginning of 1950s with the first radioiodine treatment, which actually was a debut for nuclear theranostics in Turkey, years before many other countries in the world. For the time being, along with radioiodine treatment, many other theranostic applications such as I-131 MIBG treatment, Lu-177/Y-90 DOTA peptide treatment, Lu-177 PSMA treatment, Y-90 microsphere treatment, and bone palliative treatment are being performed in many centers countrywide. As science and technology improves, novel theranostic applications are eagerly awaited to be introduced in near future. This paper summarizes the story of nuclear theranostics in Turkey and aims to give an overview on the current status of theranostic applications in Turkey.

Exploring the unknown is one of the key factors that lead to great discoveries in mankind history.With the advances in medicine and the development of new approaches towards patient care, like next-generation sequencing and patient-centered care, the need for treatments tailored to patient through personalized medicine has become more compelling. Theranostics has been introduced as a combination of a diagnostic tool and a therapeutic tool on the same vector for a specific disease, to facilitate personalized medicine. Nuclear medicine has shown the capability of providing a strong platform for this new approach through its arms, molecular imaging, and targeted molecular therapies. Though the prototype of theranostics has been practiced in Jordan since decades in the field of diagnosis and treatment of well-differentiated thyroid cancer, recently, the King Hussein Cancer Center (KHCC), a leading and comprehensive cancer center in Jordan and in the Middle East, has leaped forward to introduce the new approaches of theranostics through the nuclear medicine applications. This paper sheds the light on the most important aspects of this new theranostics practice in Jordan such as peptide receptor radionuclide therapy (PRRT) and prostate-specific membrane antigen (PSMA)–based theranostics.
