Perceptions towards climate change, water scarcity and adaptation strategies: Case of the Zerafshan River Basin in Uzbekistan
Authors: Babakholov Sherzod , Hasanov Shavkat
Published: December 2024

Adapting to climate change under different agro-ecologies of Central Asian countries still remains a matter of debate. The present study aimed to explore the perceptions and key factors influencing adaptation strategies through the stepwise appraisal framework in upstream zones of the Zerafshan River Basin in Uzbekistan. First, a Severity Index (SI) was calculated to evaluate the perceptions of farmers towards climate change and water scarcity. Then, determinants of adaptation practices were investigated using a binary Logistic regression model with comprehensive farm-level survey data collected from 307 farmers. The highest value of the SI coefficient was attained for the perception “Water resource is getting scarce”, which implies that most farmers already have worries about the potential risk of water shortages although they have been operating with an adequate water supply. Education of household head, extension, and farmer’s perceptions on climate change and water were found to be positive determinants but land size and membership in agro-clusters were found to be negatively influenced factors to climate adaptation strategies. Therefore, we suggest policy implications to consider the land size, cooperation of farmers with clusters, extension, and water management systems to increase the resilience of farmers against climate change at national level.

Authors: Yang Xinghong
Published: December 2024

COVID-19, caused by the SARS-CoV-2 virus, has resulted in nearly 7 million deaths globally as of 2023 and remains a significant health challenge. Many patients continue to suffer from long-term complications, commonly known as "long COVID," for which no definitive cure has been found. This has prompted a surge in research on potential underlying mechanisms of immunity. In addition to scientific advancements, holistic approaches to recovery are gaining attention. This study explored the application of the Guan Yin Citta Dharma Door, a Buddhist practice, in addressing both COVID-19 infection and its post-infection sequelae. By presenting a case study using this method, we examined the role of karma and collective retribution in the manifestation and healing of COVID-19. The findings suggest that integrating Dharma practices may complement conventional medical treatments, providing a holistic path to recovery for COVID-19 survivors.

Published: December 2024

Background: Cirrhosis is a chronic liver condition characterized by significant morbidity and mortality. Hepatic encephalopathy (HE), a neuropsychiatric complication of cirrhosis, is associated with vitamin D deficiency, which may exacerbate liver dysfunction. Understanding the clinical and laboratory characteristics of cirrhotic patients with and without HE is crucial for improving management strategies. Objective: To evaluate the clinical characteristics of cirrhotic patients and investigate the association between serum 25-hydroxyvitamin D levels and the severity of HE. Methods: This cross-sectional observational study was conducted at Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, from December 2019 to August 2020. A total of 54 cirrhotic patients were divided into two groups: 27 with HE (cases) and 27 without HE (controls). Clinical history, physical examination, and laboratory parameters, including serum 25-hydroxyvitamin D levels, were assessed. Data analysis involved chi-square tests, t-tests, and ANOVA, with a significance level of p < 0.05. Results: The mean age of participants was 50.2 years, with a male predominance (63%). Serum 25-hydroxyvitamin D levels were significantly lower in patients with HE (6.6 ± 2.1 ng/ml) compared to controls (13.6 ± 4.2 ng/ml; p < 0.0001). Vitamin D levels decreased progressively with higher HE grades. Cases exhibited significantly higher serum bilirubin, prothrombin time, INR, Child-Pugh scores, and MELD scores than controls (p < 0.05). Conclusion: Vitamin D deficiency is strongly associated with the severity of HE in cirrhotic patients. Lower vitamin D levels correspond to higher grades of encephalopathy, emphasizing its potential role in HE pathophysiology. Future studies should explore the therapeutic implications of vitamin D supplementation in this population.

Authors: Pontalapati Venkataramana  , Dr. Chaganti RamiReddy
Published: December 2024

Healthcare is essential for human development, improving productivity, and reducing the socio-economic burden of diseases. Despite progress in economic growth, India struggles with healthcare accessibility, particularly for vulnerable populations. The Ayushman Bharat Pradhan Mantri Jan Arogya Yojana (AB PM-JAY) and Dr. NTR Vaidya Seva are two significant health insurance schemes designed to address this challenge. AB PM-JAY, the world’s largest publicly funded health insurance program, offers cashless coverage for secondary and tertiary care, aiming to reduce catastrophic health expenditure nationwide. Dr. NTR Vaidya Seva, specific to Andhra Pradesh, targets Below Poverty Line (BPL) families with comprehensive coverage for critical health conditions. This study evaluates the potential convergence of these two schemes to maximize healthcare delivery. It explores how the integration of PM-JAY and Dr. NTR Vaidya Seva can enhance accessibility, streamline administrative processes, and improve health outcomes by providing more comprehensive and coordinated services. The trust model underpinning both schemes ensures transparency, efficient fund allocation, and quality control while promoting sustainability and adaptability. Findings indicate that convergence can reduce overlapping administrative efforts, expand coverage, and foster collaboration among stakeholders. The unified approach supports equitable healthcare access, mitigates financial barriers, and ensures resource optimization. This study underscores the transformative impact of leveraging both national and state initiatives, offering a roadmap for achieving universal health coverage and addressing India's dual burden of communicable and non-communicable diseases. Enhanced synergy between PM-JAY and Dr. NTR Vaidya Seva can significantly uplift the health scenario for millions, particularly for those most vulnerable.

Authors: Andreeva Anastasiya , Manzhurenko Yuliya
Published: December 2024

The objective of the study is to develop a recipe and technology for producing a marshmallows product using vegetable protein without animal protein. Aquafaba was used as the vegetable protein. Objectives: to develop a recipe and technology for producing a marshmallows product using aquafaba; to study the effects of aquafaba on the rheological properties of the finished product; to evaluate the organoleptic and physicochemical quality indicators; to determine the optimal dosage of aquafaba; to determine the effect of aquafaba on the shelf life of the finished product. The objects of the study were aquafaba, a semi-finished product in the form of a marshmallows mass, and a finished marshmallows product. Samples of glue-free whipped marshmallows were made with different dosages of aquafaba as a foaming agent and compared with a control sample using egg white. The volume of the marshmallows mass was determined by whipping all the ingredients in a KENWOOD KMC 500 mixer at 600 rpm in a graduated bowl for 7 minutes. After whipping, the volume of the mass was noted along the meniscus on the bowl. To determine the density of the marshmallows mass, weighing bottles with the pastille mass and distilled water were weighed and calculations were made. The mass fraction of moisture in finished products was determined by drying according to GOST 5900-2014. The texture analyzer structurometer ST-2 was used to study the rheological characteristics. The “accelerated aging” method was used to study the shelf life of the product. Organoleptic assessment of quality indicators was carried out according to GOST 6441-2014. The results of the study showed that the optimal sample was the one with an aquafaba addition dose of 56 g. The choice was based on the results of the organoleptic assessment, physicochemical indicators and rheological properties of the product. The technology for preparing marshmallows on vegetable protein was practically no different from the unified technology on egg white. When analyzing the structural and mechanical pro¬perties of finished products, it was revealed that marshmallows on aquafaba has greater elasticity and hardness than the control sample.

The objective of research is to establish changes in the phytosanitary situation in the grain-row crop rotation when introducing fallow land into agricultural circulation using the principles of organic farming in the Chulym-Yenisei forest-steppe. The object of research is a crop rotation link (wheat–wheat–corn). The stu¬dies were conducted in 2021–2023 on the territory of land use of Rodnik LLC in the Balakhta District of the Krasnoyarsk Region on a 27-year-old fallow land introduced into agricultural circulation. The studied varieties of spring wheat Novosibirskaya 31, Novosibirskaya 16, Granni. Data on the number and species composition of pests, the prevalence of diseases and weeds in crops are presented. The number of pests was significantly lower than the economic threshold of harmfulness even with the repeated inclusion of wheat in crop rotation and amounted to an average of 8.3 thrips, 1 frit fly, and 2.3 meadow moth caterpillars per 100 net swings. In the first year of fallow land use, soil suppression was noted: the level of soil colonization by Bipolaris sorokiniana at the beginning of the growing season was 20 pcs/g of soil, decreasing to 10 pcs/g of soil by the end of the growing season. In the second year of the study, root rot was noted with a prevalence of 11.5–24.4 % during the tillering phase, septoria leaf spot during the heading phase – 25 %, ear diseases on the Novosibirskaya 16 variety – 57 %, on the Novosibirskaya 31 and Granni varieties – 44.3 and 38.4 %, respectively. A decrease in the number of weed species was shown by the years of agricultural use of the fallow land: 11, 10, 8 species, respectively, in 2021, 2022, 2023. The average number of weeds per 1 m2 increased and amounted to 44.3 pcs/m2 (2021), 84 (2022) and 442.0 pcs/m2 (2023). Over the three years of the study, the proportion of root-suckering perennial weeds increased significantly compared to the first year of the study.

Published: December 2024

Large language models (LLMs) have rapidly emerged as transformative tools across multiple domains, including healthcare. The ability of LLMs to process vast amounts of data and generate human-like responses has facilitated their integration into patient care, particularly in enhancing communication, improving patient satisfaction, and streamlining administrative processes. Despite this potential, there are concerns regarding their accuracy, reliability, and ethical use in clinical settings. This scoping review aims to investigate and map the current literature on the use of LLMs in improving provider–patient experience and interaction efficiency. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines, we conducted a systematic search of Ovid MEDLINE, PubMed, and Google Scholar databases to identify relevant articles published between January 2015 and June 2024. Of the 3568 articles initially screened, 47 satisfied the inclusion criteria. These articles spanned 13 countries and encompassed diverse healthcare settings. Thematic areas of LLM utilization included improving communication between patients and healthcare providers, resolving patient inquiries, enhancing patient education, and increasing operational efficiency. Although numerous studies have yielded positive outcomes, significant challenges related to data accuracy, hallucinations, bias, and ethical concerns remain. LLMs can considerably improve patient experience in healthcare, particularly in areas of communication, education, and administrative efficiency. However, concerns regarding accuracy, ethical implications, and the need for rigorous safeguards to prevent misinformation impede their widespread adoption. Future research should focus on developing context-specific LLMs tailored to healthcare environments and addressing the identified limitations to optimize their implementation in clinical practice.
