The impact of social determinants of health on international migrants’ health outcomes: a bibliometric analysis

PurposeThe aim of this study is to conduct an in-depth exploration of the research landscape concerning the impact of social determinants of health (SDH) on the health outcomes of international migrants.Design/methodology/approachLeveraging the extensive Scopus database, this study retrieved a total of 2,255 articles spanning the years 1993–2023. The framework for analysis used the SDH categories outlined by the World Health Organization.FindingsThe research landscape exhibited an apparent increase in the number of publications, but not a net increase in the research productivity. The USA emerged as the leading contributor to research output, with the Journal of Immigrant and Minority Health emerging as the most prolific publication venue, and the University of Toronto ranking as the most prolific institution. The SDH category that received the highest number of publications was the “community and social context”. Migrants from different regions in Asia (East, Central and South Asia) and those from Latin America and the Caribbean region appeared to be the most commonly researched. Highly cited articles predominantly delved into mental health outcomes arising from discrimination and migration policies.Research limitations/implicationsThe findings proffer valuable insights for shaping future research endeavors, accentuating the imperative for diversified studies encompassing underrepresented domains, broader health outcomes and the inclusion of migrant populations from different world regions in investigative pursuits.Originality/valueThis study delivers a comprehensive analysis of the research landscape, unveiling critical trends in the realm of SDH and migrant health outcomes.

Indian and Chinese Origins of West African Village Chickens as Revealed by Mitochondrial DNA Partial D-Loop Regions

The study assessed the maternal genetic origins of West African village chickens using a 920-bp mtDNA D-loop region fragment of 127 samples from four populations (Gambia, Togo, Liberia and Nigeria). The mtDNA D-loop region was amplified following standard PCR protocols, using AV1F2: 5′-AGGACTACGGCTTGAAAAGC-3′ and 5′-TGCTTAAGGTTAATTACTGCTG-3′. as the forward and reverse primers respectively. Sequencing was done using Sanger’s dideoxy chain termination method. In addition, 268 sequence samples harvested from Genbank representing Gallus gallus from Africa, Mediterranean and different regions of Asia, were included in the analysis, bringing the total sample size to 395. 24 polymorphic sites and 13 West African chicken haplotypes (WAC1-13) were detected. The evolutionary relationships amongst studied populations and other African and global chicken populations were investigated using MEGA 7 and NETWORK 4.6 softwares. The results grouped 11 of the haplotypes including the dominant one (WAC1) with India, Pakistan and Egypt into haplogroup E, indicating an Indian sub-continental origin and Egypt as an entry point, while the other haplotypes (WAC8 and 10) clustered with haplogroup B widely believed to be of Chinese matrilineage and reported for the first time in West Africa by this study. Haplogroup B is thought to be a heritage of recent introgression of exotic alleles from commercial lines. The study shows that India and China were most likely geographic origins of the matriarchs of the West African village chickens.

A comprehensive dataset of luminescence chronologies and environmental proxy indices of loess-paleosol deposits across Asia

Loess-paleosol sequences have been used in Asia to study climate and environmental changes during the Quaternary. The scarcity of age control datasets and proxy indices analysis data for Asian loess has limited our understanding of loess depositional processes and the reconstruction of paleoclimatic changes from loess-paleosol records. In this study, we present a dataset that includes 1785 quartz optically stimulated luminescence ages and 1038 K-feldspar post-infrared infrared stimulated luminescence ages from 128 loess-paleosol sequences located in different regions of Asia. We generate 38 high-resolution age-depth models of loess records based on the provided datasets. We provide data on 12,365 grain size records, 14,964 magnetic susceptibility records, 2204 CaCO3 content records, and 3326 color reflection records. This dataset contains the most detailed and accurate chronologies and proxy index data for loess records in Asia yet published. It provides fundamental data for understanding the spatial-temporal variations in loess depositional processes and climatic changes across the continent during the mid-late Quaternary.

Cross-sectional dependence in financial openness and its influence on renewable energy consumption in Asia

Renewable energy is known for its lower environmental impact compared to conventional fossil fuels. The integration of financial openness plays a pivotal role in driving renewable energy consumption. The existing literature has predominantly overlooked the nonlinear impact of financial openness on renewable energy consumption. This study examines the nonlinear impact of financial openness on renewable energy consumption across different regions in Asia, such as Central Asia, East Asia, South Asia, Southeast Asia, and West Asia, by employing linear and nonlinear cross-sectionally augmented autoregressive distributed lag techniques. The findings of the linear analysis confirm that financial openness favorably impacted renewable energy consumption in the long run in all regions. On the other side, the nonlinear analysis highlights that an increase in financial openness promotes renewable energy consumption in all regions except West Asia. In contrast, the fall in financial openness hurt renewable energy consumption in Asia, Central Asia, and West Asia. Greenhouse gas emissions and GDP promote renewable energy consumption in almost all regions in both linear and nonlinear analysis, and ICT and trade help the consumption of renewable energy to rise in some regions. Policymakers in Asia and its subregions should focus on increasing the collaboration between the financial sectors of the Asian economies and increasing the flow of funds to renewable energy sources in Asia.

ANALYSIS OF NUTRITIONAL QUALITY AND BIOACTIVE COMPONENTS OF CISSUSROTUNDIFOLIA, CYPHOSTEMMA DIGITATUM AND CISSUS QUADRANGULARIS (VITACEAE)

Cissus rotundifolia, Cyphostemma digitatum, and Cissus quadrangularis which belong to Vitaceae family are used as local traditional vegetables by local communities in Saudi Arabia and different regions in Asia for nutritional and therapeutic purposes. They were analyzed in this study in order to provide scientific evidence for their usage as nutritional and medicinal herbs. The protein, fat, fibre, cyanogenic glycoside, phytic acid, flavonoid, and tannin contents of the three species differed significantly (P < 0.05). Results from the nutritional analysis revealed the richness of C. rotundifolia leaves in crude protein (14.54%), carbohydrates (52.32%), fats (6.99%), and energy value (330.35 Kcal/100 g). C. rotundifolia and C. digitatum leaves showed comparable amounts of both vitamins C and A. The highest crude fiber was found in C. quadrangularis (23.82%), which also exhibited a good carbohydrate content (57.20%). Calcium was the most abundant mineral in the studied whole leaf extracts, followed by potassium. C. quadrangularis contained the highest concentrations of sodium (236 mg/100 g), iron (29 mg/100 g) and the lowest level of magnesium (96 mg/100 g). The concentrations of heavy metals in all samples were below the permissible level in food. In terms of anti-nutritional factors, all extracts had comparatively low levels of cyanogenic glycoside, phytate, alkaloid, and saponin contents. The leaves of C. quadrangularis contained significantly high levels of phenol, flavonoid, tannin, and proanthocyanidin content. C. rotundifolia leaves had a high level of DPPH radical quenching power (IC50 = 52.27 µg/mL) that was comparable to that of the standard (IC50 = 51.47 µg/mL). Inhibitory activities against alpha-amylase significantly varied among the extracts analyzed. The leaves of C. quadrangularis strongly inhibited alpha-amylase, and their impact was close to the effect of acarbose as a standard anti-diabetic agent. The findings revealed that the studied leafy wild plants can be used as a good source of various nutrients and beneficial biochemicals.

The causality between air transport and economic growth: Empirical evidence from regions in Asia

This study examines the causality between air transport (passenger and cargo) and economic growth among regions in Asia. Using panel data from 1975 to 2019, the study applies econometric methods to test the stationarity and cointegration of the data, followed by the Granger causality test, and finally estimates the effect coefficients. The effect coefficients are estimated by the panel autoregressive distributed lag model (ARDL) and robustness tests by comparison with panel least squares (LS) methods. The study results confirm a bi-directional causality relationship in most regions of Asia. However, the study only confirms a unidirectional relationship from economic growth to air passenger transport in South Asia and from economic growth to air freight in Central Asia and West Asia. In addition, specific effect coefficients between air transport and economic growth in the long-run and short-run are also established in regions where they have a causal relationship. These findings serve as a basis for the development of air transport policy in different regions of Asia.

Pan-Asian adapted ESMO Clinical Practice Guidelines for the diagnosis, treatment and follow-up of patients with endometrial cancer

The most recent version of the European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of patients with endometrial cancer was published in 2022. It was therefore decided, by both the ESMO and the Indian Society of Medical and Paediatric Oncology (ISMPO), to convene a virtual meeting in July 2022 to adapt the ESMO 2022 guidelines to take into account the variations in the management of endometrial cancer in Asia. These guidelines represent the consensus opinion of a panel of Asian experts representing the oncological societies of China (CSCO), India (ISMPO), Indonesia (ISHMO), Japan (JSMO), Korea (KSMO), Malaysia (MOS), the Philippines (PSMO), Singapore (SSO), Taiwan (TOS) and Thailand (TSCO). Voting was based on scientific evidence and was conducted independently of the current treatment practices and treatment access constraints in the different Asian countries, which were discussed when appropriate. The aim of this guideline manuscript is to provide guidance for the optimisation and harmonisation of the management of patients with endometrial cancer across the different regions of Asia, drawing on the evidence provided by Western and Asian trials whilst respecting the variations in clinical presentation, diagnostic practices including molecular profiling and disparities in access to therapeutic options, including drug approvals and reimbursement strategies.

Skull, mandible and hyoid apparatus in the Indian grey mongoose (Herpestes edwardsii): A comprehensive anatomical study.

Mongooses are small carnivores residing in different regions of Asia. The Indian grey mongoose (Herpestes edwardsii) is one of the species mostly found in Iran. The skull gives the head of animal species' phylogenetic appearance and protects vital organs such as the brain and eyes. Our study aimed to enrich the current data pool by providing a morphological and morphometric description of the Indian grey mongoose's skull, mandible and hyoid apparatus. The present work was conducted on ten skulls and mandibles of the mongoose to describe the skull's anatomy and mandible grossly and radiographically. The radiographic characteristics of the Indian grey mongoose skull and mandible were demonstrated in lateral and dorsoventral projections. They were studied anatomically, and the measurements of morphometric characteristics were performed. Unpaired t-tests were used to investigate the sexual dimorphism regarding skull measurements between sexes. This study showed that the neuro-cranium area was extensive in the Indian grey mongoose skull, and the orbit was utterly bony. The presence of a two-part tympanic bulla and the absence of a distinct jugular process are also significant. In terms of the morphometric characteristics, there were significant differences between males and females, especially in the total length of the skull. Morphologically, the anatomy of the skull, mandible and hyoid apparatus is similar in male and female mongooses and follows the species' behavioural and nutritional characteristics. Some of these characteristics are different from other carnivores, especially dogs.

The Issues and Realities of BRT Planning Initiatives in Developing Asian Cities

Successful Bus Rapid Transit (BRT) planning initiatives in Latin American cities involved complex interactions among stakeholders, politicians and planners. Asian cities under different geo-political settings may not be able to achieve successful BRT planning initiatives under similar circumstances. This paper reviews the recent mass transit planning initiatives, especially BRT planning initiatives, in Asian cities and identifies the issues and realities of such initiatives in different regions of Asia. The prospect, suitability and importance of BRT as a sustainable mass transit system for Asian cities are also discussed. Guidelines are suggested for probable successful BRT planning initiatives under different geo-political contexts of Asian cities.

Saccharides as Particulate Matter Tracers of Biomass Burning: A Review.

The adverse effects of atmospheric particulate matter (PM) on health and ecosystems, as well as on meteorology and climate change, are well known to the scientific community. It is therefore undeniable that a good understanding of the sources of PM is crucial for effective control of emissions and to protect public health. One of the major contributions to atmospheric PM is biomass burning, a practice used both in agriculture and home heating, which can be traced and identified by analyzing sugars emitted from the combustion of cellulose and hemicellulose that make up biomass. In this review comparing almost 200 selected articles, we highlight the most recent studies that broaden such category of tracers, covering research publications on residential wood combustions, open-fire or combustion chamber burnings and ambient PM in different regions of Asia, America and Europe. The purpose of the present work is to collect data in the literature that indicate a direct correspondence between biomass burning and saccharides emitted into the atmosphere with regard to distinguishing common sugars attributed to biomass burning from those that have co-causes of issue. In this paper, we provide a list of 24 compounds, including those most commonly recognized as biomass burning tracers (i.e., levoglucosan, mannosan and galactosan), from which it emerges that monosaccharide anhydrides, sugar alcohols and primary sugars have been widely reported as organic tracers for biomass combustion, although it has also been shown that emissions of these compounds depend not only on combustion characteristics and equipment but also on fuel type, combustion quality and weather conditions. Although it appears that it is currently not possible to define a single compound as a universal indicator of biomass combustion, this review provides a valuable tool for the collection of information in the literature and identifies analytes that can lead to the determination of patterns for the distribution between PM generated by biomass combustion.

Clinical Profiles of Asians with NAFLD: A Systematic Review and Meta-Analysis

Introduction: NAFLD is increasingly prevalent in Asia, where people suffer more metabolic comorbidities at a lower body mass index (BMI), suggesting potential differences in their clinical profile. Therefore, we attempted to characterize the clinical profile of Asians with NAFLD via a meta-analytic approach. Methods: We searched PubMed, EMBASE, and Cochrane databases from January 1, 2000, to January 17, 2019. Two authors independently reviewed and selected 104 articles (2,247,754 persons) that identified NAFLD in Asians and reported relevant data, especially BMI and ALT, and excluded individuals with other liver disease and excessive alcohol consumption. Individual patient-level data were obtained from seven cohorts in Asia to complement meta-analyzed data. Results: Overall, the mean age was 52.07 (95% CI: 51.28–52.85) years, with those from Southeast Asia (42.66, 95% CI: 32.23–53.11) being significantly younger. The mean BMI was 26.2 kg/m², higher in moderate-severe versus mild hepatic steatosis (28.3 vs. 25.7) patients and NFS ≥ −1.455 versus <−1.455 (27.09 vs. 26.02), with 34% having nonobese NAFLD. The mean ALT was 31.74 U/L, higher in NFS < −1.455 versus ≥−1.455 (33.74 vs. 27.83), though no differences were found by obesity or steatosis severity. The majority of males (85.7%) and females (60.7%) had normal to minimally elevated ALT (1–1.5 × 95% ULN). Individual patient-level data analysis (N = 7,668) demonstrated similar results. Conclusion: About one-third of Asians with NAFLD were nonobese, and the majority did not have markedly elevated ALT. Therefore, abnormal ALT or BMI is not recommended as a criterion for NAFLD screening in this population. Additionally, there were significant differences in the clinical profiles of NAFLD among the different regions of Asia.

The Relationship Between Compulsive Buying and Hoarding in China: A Multicenter Study.

There is no previous research that has explored the correlation between compulsive buying and hoarding in the Chinese population. This study aims to determine the relationship between compulsive buying and hoarding in a sample of the Chinese population comprising participants from mainland China (emerging economy) and Hong Kong (developed economy). Self-reported measures consisting of demographic questions, the Chinese version of the Hoarding Rating Scale (CHRS), and Richmond Compulsive Buying Scale-Traditional Chinese (RCBS-TC) were administered to participants. After data collection, common method biases were precluded. The RCBS-TC and CHRS were validated by confirmatory factor analysis and found correlated by Pearson correlation coefficient. The RCBS-TC and CHRS demonstrated satisfactory levels of internal consistency (Cronbach’s α = 0.872 and 0.828, respectively). A three-factor model, including hoarding, obsessive-compulsive, and impulse control disorders, was obtained through Confirmatory Factor Analysis (CFA) with the satisfactory fit for the total sample from Hong Kong and mainland China. A significant correlation was found between RCBS-TC and CHRS (r = 0.473). Findings also showed that 14% of the participants exhibited compulsive buying behavior. This study provides sufficient proof of the reliability and validity of RCBS-TC and CHRS. Their relationship was explored based on two sets of samples from different regions in Asia, which contributes more applicability in a cross-cultural context.

A Review on the Medicinal Potential of Trachyspermum ammi Found in Pakistan

Numerous plants are used as a traditional medicine in herbal therapy and are well known for their effective potential in therapeutics for different ailments. Carom [Trachyspermum ammi] is one of the plants that are crucial in medicine. It was cultivated first time in different regions of Asia. It has been used in traditional medicine for a long time in a variety of pharmacological and medicinal aspects. It is renowned for its curative value in different miseries, especially infections. Like other fatal diseases, great advancements have been made by utilizing the therapeutic abilities of different medicinal plants regarding the cure and control of cancer progression. However still, there is a need for improvement in treatment strategies and meeting up significant deficiencies in cancer management. Carom may have some progressive role in controlling such types of ailments. Moreover, it may be anticipated as an immunotherapeutic agent and would dominate other infection-controlling agents and cancer-treating strategies due to its higher efficiency as well as biosecurity free of adverse side effects.

Can changes in education alter future population ageing in Asia and Europe?

While population ageing is rising, the educational composition of the elderly remains rather heterogeneous. This study assesses the educational differences in future population ageing in Asia and Europe, and how future population ageing in Asia and Europe would change if the educational composition of its populations changed. A comparative population ageing measure (the Comparative Prospective Old-Age Threshold [CPOAT]) was used, which recalculates old-age thresholds after accounting for differences in life expectancy, and the likelihood of adults surviving to higher ages. Combined data from projected age- and sex-specific life-tables (from the United Nations) and projected age- and sex-specific survival ratios by different levels of education (from the Wittgenstein Centre for Demography and Global Human Capital) were used to construct projected life-tables (2015-2020, …, 2045-2050) by educational level and sex for different regions of Asia and Europe. Based on these life-tables, future comparative prospective old-age thresholds by educational level and sex were calculated. It was found that in both Asia and Europe, and among both men and women, the projected old-age thresholds are higher for higher educated people than for less-educated people. While Europe has a larger projected share of elderly in the population than Asia, Europe's older population is better educated. In alternative future scenarios in which populations hypothetically have higher levels of education, the projected shares of elderly in the population decrease across all regions of Asia and Europe, but more so in Asia. The results highlight the effectiveness of investing in education as a policy response to the challenges associated with population ageing in Asia and Europe. Such investments are more effective in the Asian regions, where the educational infrastructure is less developed.

Estimating Artificial Impervious Surface Percentage in Asia by Fusing Multi-Temporal MODIS and VIIRS Nighttime Light Data

Impervious surfaces have important effects on the natural environment, including promoting hydrological run-off and impeding evapotranspiration, as well as increasing the urban heat island effect. Obtaining accurate and timely information on the spatial distribution and dynamics of urban surfaces is, thus, of paramount importance for socio-economic analysis, urban planning, and environmental modeling and management. Previous studies have indicated that the fusion of multi-source remotely sensed imagery can increase the accuracy of prediction for impervious surface information across large areas. However, the majority of them are limited to the use of specific data sources to construct a few features with which it can be challenging to characterize adequately the variation in impervious surfaces over large areas. Thus, impervious surface maps are often presented with high uncertainty. In response to this problem, we proposed the use of multi-temporal MODIS and Visible Infrared Imaging Radiometer Suite (VIIRS) nighttime light data to construct a more general and robust feature set for large-area artificial impervious surface percentage (AISP) prediction. Three fusion methods were proposed for application to multi-temporal MODIS surface reflectance product (MOD09A1) and Visible Infrared Imaging Radiometer Suite (NPP-VIIRS) Day/Night Band (DNB) data to construct three different types of features: spectral features, index features (band calculations), and fusion features. These features were then used as variables in a random-forest-based AISP prediction model. The model was fitted to China and then applied to predict AISP across Asia. Fifteen typical cities from different regions of Asia were selected to assess the accuracy of the prediction model. The use of multi-temporal MODIS and VIIRS DNB data was found to significantly increase the accuracy of prediction for large-area AISP. The feature set constructed in this research was demonstrated to be suitable for large-area AISP prediction, and the random forest model based on optimization of the selected features achieved the highest accuracy, amongst benchmarks, with testing R2 of 0.690, and testing RMSE of 0.044 in 2018, respectively. In addition, to further test the performance of the proposed method, three existing impervious products (GAIA, HBASE, and NUACI) were used to compare quantitatively. The results showed that the predicted AISP achieved superior performance in comparison with others in some areas (e.g., arid areas and cloudy areas).

Reduce Disease Burden of Human Schistosomiasis in Asia Through Biological Control.

Schistosomiasis is a chronic parasitic disease caused by a trematode blood fluke of the genus Schistosoma that belongs to the Schistosomatidae family. It is a neglected disease in different regions of Asia. In this review, 218 articles (between 2000 and 2017) related to the topic were collected from PubMed and Google scholar and reviewed. After thoroughly reading collected articles, due to irrelevant topic requirements, 94 articles were excluded. Articles that have data associated with Asian regions are considered. In Asia, the disease is prevalent in China, Philippines, Indonesia, Yemen, Nepal and Laos, etc. While in Pakistan, India and Bangladesh, the disease is not endemic and very few cases were reported. The disease was eliminated from Japan and Iran. The current review highlights the geographical distribution among Asian countries, transmission patterns, diagnosis, control strategies based on the use of anthelmintic plants and management practices implemented in Asia for the control of schistosomiasis. However, new implementations to treat schistosomiasis in humans should be proved to eliminate the disease finally in the future. This review emphasizes the biological control of schistosomiasis for the eradication of the disease from Asia in the near future.

After exploring the nature of links between the two fields, it reflects on globalisation, looks at the prominent theories in international relations critically before moving on to discuss areas such as Latin America and Sub-Saharan Africa. Further, by shedding light on inter-area relations, it grapples to find a way to define an area. By treating India as an area in its own right, it relates India to different regions of Asia. It essentially argues that scholars in India need to evolve innovative concepts and theories by doing inter-disciplinary research that are useful for knowledge building exercises as well as policy think tanks.

KNOWLEDGE BASED CLASSIFIER BASED ON BACKSCATTERING COEFFICIENT FOR MONITORING THE CROP GROWTH ANALYSIS USING MULTI-TEMPORAL IMAGES OF SPACE-BORNE SYNTHETIC APERTURE RADAR (SAR) SENSORS

Abstract. Space-based observation of crops and agro-system on the Earth surface is one of the most important applications of remote sensing using the sensors in optical and microwave spectrum to assess the crop growth for decision making for developing crop information and management system. Remote sensing technology provides scalable and reliable information in respect of rice crop grown area, its crop growth and prediction of crop yield due to acquisition of satellite imagery during the revisit of the orbit by space-borne sensors in optical and microwave spectrum. Synthetic Aperture Radar has the advantages of all-weather, day and night imaging, canopy penetration, and high-resolution capabilities, which makes Space-borne SAR sensors as an effective system for monitoring crop growth, crop classification and mapping of crop area based on the crop canopy interaction of SAR signals due to backscattering coefficients of the earth surface. SAR data from ERS-1/2 SAR, ENVISAT ASAR, ALOS-1/2 PALSAR, Radarsat-1/2 SAR, TerraSAR, COSMO-SkyMed, and Sentinel-1 have been used by various researchers for identification and analysis of rice crop growth based on the backscattering values in different regions of Asia and European region, where backscattered image depends of various earth surface and SAR sensors parameters. In this paper, knowledge based classifier using SAR images of existing space-borne-SAR sensors have been developed based on modeling of SAR backscattering coefficients in C-band and X-band for monitoring the rice crop growth and its analysis using multi-temporal and multi-frequency- SAR sensors data.
