A drought is when reduced rainfall leads to a water crisis, impacting daily life. Over recent decades, droughts have affected various regions, including South Sulawesi, Indonesia. This study aims to map the probability of meteorological drought months using the 1-month Standardized Precipitation Index (SPI) in South Sulawesi. Based on SPI, meteorological drought characteristics are inversely proportional to drought event intensity, which can be modeled using a Non-Homogeneous Poisson Process, specifically the Power Law Process. The estimation method employs Maximum Likelihood Estimation (MLE), where drought event intensities are treated as random variables over a set time interval. Future drought months are estimated using the cumulative Power Law Process function, with the β and γ parameters more significant than 0. The probability of drought months is determined using the Non-Homogeneous Poisson Process, which models event occurrence over time, considering varying intensities. The results indicate that, of the 24 districts/cities in South Sulawesi, 14 experienced meteorological drought based on the SPI and Power Law Process model. The estimated number of months of drought occurrence in the next 12 months is one month of drought with an occurrence probability value of 0.37 occurring in November in the Selayar, Bulukumba, Bantaeng, Jeneponto, Takalar and Gowa areas; in October in the Sinjai, Barru, Bone, Soppeng, Pinrang and Pare-pare areas; as well as in December in the Maros and Makassar areas.

The Hengduan Mountains, situated on the southeastern edge of the Qinghai-Tibet Plateau, are the longest and widest north-south-oriented mountain range in China, exerting a significant influence on the ecological and geographical pattern. Understanding the topographic and geomorphological characteristics of the Hengduan Mountains is fundamental and crucial for research in related fields such as ecology, geography, and sustainability. In this study, Digital Elevation Model (DEM) data were utilized to extract and analyze the topography and geomorphology (TG) pattern. TG maps have been developed to quantitatively classify the TG types in the Hengduan Mountains by combining the five factors of elevation, slope, aspect, relief and landform. The spatial distribution and quantitative characteristics of these factors were mapped and investigated using geographic information systems. The results revealed that: (1) The Hengduan Mountains exhibit an elongated north-south distribution, with an average elevation of approximately 3746 m, an average slope of around 25°, and an average relief of about 266 m. (2) The Hengduan Mountains display significant elevation differences, with an overall high elevation, characterized by a trend of lower elevation in the east and higher elevation in the west, as well as irregular orientations of various aspects. (3) The 19 landform types were identified; the landform types of the Hengduan Mountains are primarily composed of low-relief high-mountains (42.0618%), low-relief mid-mountains (22.4624%), and high-elevation hills (20.5839%). The results of the study can provide data and information support for the ecology, environmental protection and sustainable development of the Hengduan Mountains.

Calcitonin level in the blood of patients with medullar thyroid cancer: association with carcinoma characteristics
Authors: Guda B. B. , Komisarenko І. І. 
Published: December 2024

The literature data on the existence of a relationship between the level of calcitonin (CT) and the presence and localization of metastases of medullary thyroid carcinoma (MTC) in the lymph nodes of the neck are ambiguous. While discussions about the diagnostic value of determining the level of CT focus on clarifying the range of its concentration increase 021in its concentration in the presence of metastases of different localization, the significance of other aggressive characteristics of MTC has received limited attention. However, such information may be useful for the prediction of recurrence or residual metastatic disease.
Objective — to determine the possible relationship between the aggressive characteristics of MTC and the level of CT in the patients’ serum with medullary cancer.
Materials and methods. A retrospective analysis of data from 82 patients with MTC who were examined and operated on between 2000 and 2024 was conducted. We analyzed the level of CT in the blood serum before and after surgery, tumor size, localization of metastases in the lymph nodes of the neck, the presence of multifocality, invasiveness and association of MTC with chronic autoimmune thyroiditis, as well as the number of patients who were diagnosed with incomplete biochemical remission after surgical treatment.
Results. The existence of a clear correlation between the size of the MTC and the level of CT in the serum of patients has been confirmed, which decreases for the residual CT content after thyroidectomy. The increase in the level of CT in the blood of patients with metastases in the central or lateral lymph nodes of the neck is significant, but does not differ from each other, and with extensive metastasis it is even less than with the localization of metastases separately in the central or lateral compartments. An association has been established between the characteristics of MTC and an increase in the level of CT in the blood serum of patients: the highest concentration of CT is observed in the case of multifocal carcinomas and tumors with extrathyroidal invasion, and the lowest in patients with non‑invasive carcinomas. Incomplete biochemical remission was most often observed in the presence of metastases and in MTC with extrathyroidal invasion.
Conclusions. The combination of different clinico‑oncological and morphological characteristics of MTC is responsible for the varying degrees of elevation of CT levels in the blood of patients with medullary cancer. The frequency of incomplete biochemical remission in patients after surgical treatment does not depend on the localization of metastases in the lymph nodes of the neck and is minimal for tumors up to 20 mm in size and non‑invasive; it was most often observed in the case of MTC with extrathyroidal invasion.

The internationally recognized non‑specific questionnaire for determining the quality of life SF‑36v2 is widely used in various fields of medicine. Despite the convenience of its use at the questionnaire stage, the complexity of the procedure for further processing the results limits the use of the questionnaire, as it requires a lot of attention and working time.
Objective — to develop a user‑friendly tool in MS Excel for processing results from the SF‑36 quality‑of‑life questionnaire, eliminating the need for specialized software.
Materials and methods. The possibility of using MS Excel spreadsheets to create a calculator for processing the questionnaire results using the SF‑36 questionnaire to calculate data obtained for a group of patients was analyzed.
Results. The calculator «Calc_SF‑36‑ukr» was developed in the MS Excel environment to process the results of the questionnaire using the SF‑36 questionnaire. The resulting tool allows you to quickly perform the necessary calculations without the direct participation of the researcher. It was established that the calculations made using the calculator «Calc_SF‑36‑ukr» are correct and correspond to the results obtained using alternative means.
Conclusions. The use of the developed calculator for processing questionnaire data using the SF‑36 significantly accelerates and simplifies the process of obtaining results. Electronic data processing reduces the number of errors associated with the human factor. The developed calculator allows for obtaining summary results for a group of patients using a single software tool. Further improvements to the developed tool will include enhancing the convenience of entering primary data, reducing the likelihood of random errors, adding a function to search for individual patient results, strengthening the protection of the calculation module from accidental changes, and more. The developed calculator can be used in scientific research and practical work.
Insulin resistance and hyperinsulinemia as pathophysiological links between thyroid cancer and obesity. Review
Authors: Brenta G. 
Published: December 2024

In recent decades, there has been a marked increase in the prevalence of thyroid cancer. The incidence of well‑differentiated thyroid cancer (TC) has been increasing dramatically over the last 20 years worldwide, and TC is expected to be the fourth most common cancer by 2030. The rapid increase in the detection rate of TC in recent years has caused many changes in the management of these malignancies. TC accounts for 3.4% of all cancers diagnosed annually worldwide. Some data suggest that TC is increasing globally much faster than other malignant lesions. This might be a consequence of the widespread use of ultrasonography (US) examination and ultrasound guided fine needle aspiration biopsy (UG‑FNAB) procedures. Generally, this observation led to a globally highlighted discussion about the causes of such a situation. Some authors say that the higher incidence of TC is due to overdiagnosis. Others believe that various additional factors may play a role in this observation, such as obesity and an increased exposure to ionizing radiation. This phenomenon has paralleled the increase in the prevalence of obesity worldwide, which is associated with insulin resistance. Associations between these entities have been hypothesized, mainly for older and female populations, but they remain unclear. The aim of this review article was to systematically review the literature in an attempt to determine whether the increase in the prevalence of thyroid cancer is due to obesity or due only to improved detection with the better imaging techniques available. A thorough literature search on PubMed and application of selection criteria identified 14 appropriate studies. The detailed analysis of the data from these studies indicated that there is a suggestive association between thyroid cancer, obesity, insulin resistance and hyperinsulinemia for both genders. Therefore, the increased prevalence of thyroid cancer is not dependent on improved detection only. Further research should be performed for complete understanding of the pathophysiological associations, especially regarding adipose tissue and genetics, but also for the improvement of preventive public health policies.

Secure Image Reconstruction using Deep Learning-based Autoencoder with Integrated Encryption Layers
Authors: Abd Ali Wurood 
Published: December 2024

This study presents an autoencoder model designed for secure image reconstruction through the integration of encryption and decryption layers within its framework. The major goal is to achieve more effective image reconstruction while safeguarding data integrity. A convolutional neural network (CNN) is first utilized as the primary architecture, attaining a reconstruction accuracy of 90.63% with 2.3737x losses. This brought an opportunity for further improvement, and thus we propose the improved model with the integration of CNN and bidirectional gated recurrent unit (BiGRU) as hybrid model. The integration of CNN-BiGRU leverages the feature extraction advantage of CNN and the temporal processing ability of BiGRU to a great improvement of reconstruction accuracy, reaching 95.57% and validation accuracy stabilizing around 0.85 at the end of training. The model exhibits great accuracy without significant overfitting, thus acquiring robust characteristics crucial for precise image reconstruction. In this work, the hybrid model outperforms the conventional CNN-only architectures for secure image reconstruction and can thus be considered a potential approach when high fidelity with security is required in processing image data.
