RESUMO
El crecimiento del número de organizaciones criminales y su complejidad, en la variedad conceptual, las implicancias teóricas y sus desafíos empíricos, han dificultado a los investigadores la generación de suficientes teorías, estudios de causas y escalas que permitan una categorización y explicación de sus fenómenos. La caracterización de estas organizaciones y el abordaje de su definición resultan complejos tanto por la diversidad de sus impactos sociales como por lo frondoso de las áreas temáticas que la abordan. Este estudio muestra las tendencias de investigación y estudio de las organizaciones criminales mediante la realización de una revisión sistemática de literatura de los años 2022 y 2023, utilizando el método PRISMA y explorando las tendencias actuales en la investigación académica y producción bibliográfica sobre el tema.
The growth in the number of criminal organisations and their complexity, in terms of conceptual variety, theoretical implications and empirical challenges, have made it difficult for researchers to generate sufficient theories, studies of causes and scales to categorise and explain the phenomena. The characterisation of these organisations and the approach to defining them is complex both because of the diversity of their social impacts and because of the broad range of thematic areas they address. This study shows the trends in research and study of criminal organisations by conducting a systematic literature review of the years 2022 and 2023, using the PRISMA method and exploring current trends in academic research and bibliographic production on the subject.

BACKGROUND:In recent years,High-definition transcranial direct current stimulation(HD-tDCS)has garnered significant attention due to its potential non-invasive modulation of brain function.However,there is still a lack of visual analysis in the literature regarding this technique. OBJECTIVE:To perform a visual analysis of HD-tDCS-related research so as to explore the current status and trends in this field. METHODS:English literature related to HD-tDCS was retrieved from the Web of Science Core Collection database covering the period from January 1,2010 to May 6,2023.The VOSviewer software was used to visualize and analyze the source journals,countries/regions,authors,institutions,cited references,and keywords of the included literature,creating a knowledge map to uncover the research landscape and hotspots. RESULTS AND CONCLUSION:A total of 336 articles were included,showing a consistent increase in the annual publication count of HD-tDCS research.Among these,the United States contributed the highest number of publications(141 articles)with 4 221 citations,followed by China with 70 articles and 401 citations.Brain Stimulation was the most prolific journal(28 articles),Marom Bikson was the most productive author(37 articles),and The City College of New York was the most active institution(35 articles).The most frequently mentioned keywords in the field included motor cortex,regulation,working memory,excitability,and dorsolateral prefrontal cortex.Notable recent keywords in the last 5 years include attention-deficit/hyperactivity disorder,brain networks,and stimulation intensity.Currently,the volume of HD-tDCS research is relatively limited,but is on an upward trajectory,indicating substantial research potential.It is expected that future studies in this domain will continue to focus on the application of HD-tDCS in cognitive and neuropsychiatric disorders,while also exploring its therapeutic mechanisms targeting the motor cortex and dorsolateral prefrontal cortex based on brain network analysis.
RESUMO
Theranostics in nuclear medicine is an important direction for the precision medicine. Radionuclide therapy based on small molecules/peptides often requires high doses. Improving the utilization efficiency of radionuclides, optimizing the pharmacokinetics of radionuclide therapeutic molecular probes as well as increasing the target to non-target ratio have become the international hot frontiers in the field of radiotheranostics. Evans blue (EB) motif uses endogenous albumin as a reversible carrier, and the small molecule and polypeptide structure modified based on EB can effectively extend the half-life in the blood and substantially increase the uptake, accumulation and retention of radiopharmaceuticals in target lesions, and thereby enhance the therapeutic effect and reduce the dosage of nuclides. This article focuses on the research of EB modified radiopharmaceuticals for theranostics.

At present, the use of DL algorithms to establish learning models for MPI images is still in the research stage, and more external verification and iterative updates are needed before it can be widely used in real time clinical practice. In this article, the application of DL algorithms in MPI is comprehensively elaborated to provide a basis and direction for further research.
RESUMO
Near-infrared (NIR) can be divided into NIR-Ⅰ (650-900 nm) and NIR-Ⅱ (900-1 700 nm) according to its wavelength. Compared with traditional NIR-Ⅰfluorescence imaging, NIR-Ⅱ fluorescence imaging has lower tissue absorption and photon scattering as well as higher tissue penetration and resolution, which is considered as the most promising optical imaging technique in clinical application. In addition, combined with multimodal or therapeutic integrated molecular probes, NIR-Ⅱ fluorescence imaging can accurately localize tumors and guide treatment, providing a remarkable modality for early diagnosis and treatment of tumors. In this review, research progress on NIR-Ⅱ fluorescence imaging in the diagnosis, monitoring of metastasis and treatment of tumors are mainly introduced.

PET/CT plays an important role in the evaluation, follow-up and monitoring of the outcome of oncological and inflammatory diseases. This article mainly summarizes the clinical applications of PET/CT in predicting the prognosis of COVID-19 infection, early detection of myocardial involvement, diagnosis of neurological complications by multiple molecular imaging, and identification of tumor axillary lymph node metastasis and inflammatory response after vaccination.
RESUMO
Thyroid cancer is one of the most common tumors of the endocrine system, characterized by high morbidity and low mortality. Thyroid stimulating hormone (TSH) is an important factor in the development of thyroid cancer. TSH suppression therapy is widely used in clinical practice to reduce recurrence and metastasis through long-term strict monitoring and control of postoperative TSH level in patients with differentiated thyroid cancer (DTC). However, the specific mechanism of the effect played by TSH in the proliferation and progression of DTC has not been clarified. The current researches focus on classifying the relation between TSH and the onset risk, adverse clinicopathological factors and prognosis of DTC, and the applicable scope of TSH suppression therapy and targeted TSH receptor (TSHR) therapy. This article reviews the relation between TSH and DTC and the latest research progress of TSH suppression therapy and TSHR targeted therapy.

RESUMO
Dual-tracer PET imaging can provide more comprehensive clinical information for disease diagnosis. How to achieve dual-tracer imaging through single imaging session is one of the hot topics in the field of nuclear medicine. The key issues in achieving dual-tracer imaging with a single scan is the accurate separation of single-tracer information from the mixed tracer signal. In the last two decades, separation methods for different tracers have been proposed, and the injection interval between two tracers was reduced. This paper summarizes recent dual-tracer separation methods. The basic principles, features and advantages of separation methods are analyzed. Besides, the outlook on the future development of dual-tracer separation is also discussed in the present review.

RESUMO
【Objective】 To review the scientific research advances in the field of preschool children′s nutrition from 2012 to 2022, in order to provide reference for relevant policy formulation and further scientific exploration in this area. 【Methods】 High-quality literature published both domestically and internationally between 2012 and 2022 was retrieved through Web of Science (WOS) and China National Knowledge Infrastructure (CNKI) database. Excel and CiteSpace software were applied to visualize the research hotspots and frontier trends. 【Results】 A total of 1 816 English articles and 110 Chinese articles were included in the analysis. The cooperation network density of research institutions and authors was found to be low. Excluding the search terms, the top three English keywords were vitamin A (0.74), intervention (0.67), obesity prevention (0.55); the top three Chinese keywords were "anemia" (0.41), "obesity" (0.38), and "nutritional status" (0.18). In Chinese and English clusters, "anemia" and "physical activity" ranked first, respectively. The latest burst words identified were "dietary pattern" and "diet quality". 【Conclusions】 The number of English literature published in the field of preschool children′s nutrition is increasing, but it has shown a downward trend in the past three years in China. There are few studies in this field in China. The research hotspots primarily focus on the nutritional status of preschool children, with less attention paid to intervention research and methodological exploration. Further research in the field of preschool children′s nutrition in China may need to focus on the external determinants of preschool children′s nutrition, such as parental education, diet and food supply.
