RESUMO

India is one of the world's largest producers of tree nuts, yet it paradoxically remains a net importer of these commodities. This study aims to analyze the demand for imported tree nuts in India, motivated by the need to understand the factors contributing to this imbalance. The primary objective is to calculate income elasticities and own- and cross-price elasticities for five categories of imported tree nuts using the linear approximate almost ideal demand system model. Data is sourced from monthly import records from the United Nations Comtrade database covering 2014 to 2022. The tree nuts considered are almonds, cashews, pistachios, walnuts, and hazelnuts. Key findings reveal all imported tree nuts are normal goods. Cashews exhibit income elasticity (1.2), indicating a significant demand increase with rising incomes, while other nuts show income inelasticity. Cashews are price-elastic (-1.3), while other nuts are price-inelastic. Compensated cross-price elasticities indicate notable substitution effects, particularly between almonds and cashews. The study recommends enhancing domestic cashew production to meet growing demand and developing targeted marketing strategies to address competitive dynamics within the tree nut market. These strategies aim to reduce India's dependency on imports and promote a balanced, sustainable domestic market.

RESUMO

Purpose: Although the Americas and Europe have historically dominated the global research landscape, emerging economies - Brazil, Russia, India, China, and South Africa (BRICS) have significantly increased their contributions in recent years. This article studies clinical trial trends in the BRICS nations between 2018 and 2022 and compares it with trends in the G7 nations (comprising Canada, France, Germany, Italy, Japan, the UK, the USA, and the European Union). This will help stakeholders in planning drug development strategies. Materials and Methods: Data were collected from the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) and the World Bank database. An electronic search was done for the total number of trials registered between January 1, 2018, and March 15, 2023. Information was analyzed based on the year of registration, therapeutic area, type of intervention, sponsorship, and type of special population. The trial density indices (TDIs) were calculated based on population (Xi) and gross domestic product (GDP) (Yi) using author-derived formulae. Results: Altogether 2, 77, 536 trials from the BRICS and G7 were registered. China and the US had the most trials among the BRICS and G7, respectively. Between 2018 and 2022, the gap between the BRICS and G7 steadily reduced. The most common indication for clinical trials among the BRICS was cancer. Based on population, the TDI was the highest in China and the lowest in Russia. In proportion to the GDP, the TDI was maximum in Russia and minimum in India. Conclusion: There is a remarkable reduction in the gap in clinical trial trends between the BRICS and G7 nations. Among the BRICS, India and China are at the forefront in drug development. There is scope for improvement in trial density based on India's population and GDP. Stakeholders are likely to utilize the strengths of the BRICS as an attractive destination for investment in this area.

RESUMO

As dengue expands globally and many vaccines are under trials, there is a growing recognition of the need for assessing T cell immunity in addition to assessing the functions of neutralizing antibodies during these endeavors. While several dengue-specific experimentally validated T cell epitopes are known, less is understood about which of these epitopes are conserved among circulating dengue viruses and also shared by potential vaccine candidates. As India emerges as the epicenter of the dengue disease burden and vaccine trials commence in this region, we have here aligned known dengue specific T cell epitopes, reported from other parts of the world with published polyprotein sequences of 107 dengue virus isolates available from India. Of the 1305 CD4 and 584 CD8 epitopes, we found that 24% and 41%, respectively, were conserved universally, whereas 27% and 13% were absent in any viral isolates. With these data, we catalogued epitopes conserved in circulating dengue viruses from India and matched them with each of the six vaccine candidates under consideration (TV003, TDEN, DPIV, CYD-TDV, DENVax and TVDV). Similar analyses with viruses from Thailand, Brazil and Mexico revealed regional overlaps and variations in these patterns. Thus, our study provides detailed and nuanced insights into regional variation that should be considered for itemization of T cell responses during dengue natural infection and vaccine design, testing and evaluation.

RESUMO

Mucormycosis is the third most frequent invasive mycosis, following candidiasis and aspergillosis. It is frequently neglected due to its rare occurrence; but recently attend the status of notifiable disease due to its higher incidence in both developed and developing nations. India has received global notice since its estimated instances were greater than the global estimated figures. Mucormycosis has several clinical manifestations, including rhino-orbital-cerebral (ROCM), pulmonary, gastrointestinal, cutaneous, renal, and diffuse Mucormycosis. ROCM is the most frequent clinical manifestation in India, although pulmonary mucormycosis is prevalent worldwide. This review also discusses host defenses, pre disposing risk factors and fungal virulence factors that impair host's ability to prevent fungus invasion and disease establishment. The diagnosis of the disease depends on clinical interventions, histological or microbiological procedures along with molecular methods to obtain timely results. But there are still unmet challenges for rapid diagnosis of the disease. Treatment of the disease is achieved by multimodal approaches such as reversal of underlying predisposing factors, rapid administration of antifungals in optimal doses and surgical procedures to remove infected tissues. Liposomal Amphotericin B, Posaconazole and Isavuconazoles are preferred as the first line of treatment procedures. clinical trials. Different studies have improved the existing drug and under clinical trials while several studies predicted the new potential targets as CotH and Ftr1 as shown in infection and in vitro models. Therefore, current scenario demands a multidisciplinary approach is needed to investigate the prevalence, pathogenesis which is highly important for the advancement of rapid diagnosis and effective treatment.

RESUMO

Salmonella is an important poultry pathogen with zoonotic potential. Being a foodborne pathogen, Salmonella-contaminated poultry products can act as the major source of infection in humans. In India, limited studies have addressed the diversity of Salmonella strains of poultry origin. This study represented 26 strains belonging to Salmonella serovars Typhimurium, Infantis, Virchow, Kentucky, and Agona. The strains were tested for resistance to 14 different antimicrobial agents using the Kirby-Bauer disk-diffusion assay. The presence of the invA, hilA, agfA, lpfA, sopE, and spvC virulence genes was assessed by polymerase chain reaction (PCR), and the genetic diversity was assessed by Enterobacterial Repetitive Intergenic Consensus Polymerase Chain Reaction (ERIC-PCR). The highest resistance to tetracycline (n = 17; 65.38%) followed by nalidixic acid (n = 16; 61.53%) was detected among the strains. Among the strains (n = 17) phenotypically resistant to tetracycline, 94% (n = 16) were also positive for the tetA gene. Based on the presence of virulence genes, the strains were characterized into three virulence profiles (PI, P2, and P3). Among the investigated virulence genes, invA, hilA, agfA, and lpfA were present in all strains. The sopE gene was mostly associated with serovars Virchow (n = 3; 100%) and Typhimurium (n = 8; 80%), whereas spvC gene was exclusive for two Typhimurium strains that lacked sopE gene. ERIC-PCR profiling indicated clusters correlating their serovar, geographical, and farm origins. These results demonstrate that Salmonella isolates with a wide genetic range, antibiotic resistance, and virulence characteristics can colonize poultry. The presence of such strains is crucial for both food safety and public health.

RESUMO

INTRODUCTION: Multimorbidity has emerged as a major healthcare challenge in low/middle-income countries (LMICs) such as India and Brazil. Life course epidemiology suggests that adverse events in early life contribute to an individual's later health in adulthood. However, little is known about the influence of early life health and social factors on the development of multimorbidity in adulthood in LMICs. We aimed to explore the association of adult multimorbidity with childhood health and social disadvantages among two LMICs, India and Brazil. METHODS: We conducted a secondary data analysis of older adults aged ≥50 years using nationally representative surveys from Longitudinal Ageing Study in India, 2017-2018 (n=51 481) and 'Estudo Longitudinal da Saude e Bem-Estar dos Idosos Brasileirous', 2015-2016 (n=8730). We estimated the prevalence of multimorbidity along with 95% CI as a measure of uncertainty for all weighted proportions. Log link in generalised linear model was used to assess the association between childhood health and disadvantages with multimorbidity, reported as adjusted prevalence ratio (APR). RESULTS: The prevalence of multimorbidity was 25.53% and 55.24% in India and Brazil, respectively. Participants who perceived their childhood health as poor and missed school for a month or more due to illness had the highest level of multimorbidity across both countries. After adjusting for age and gender, a significant association between adult multimorbidity and poor self-rated childhood health (APR: (India: 1.38, 1.16 to 1.65) and (Brazil: 1.19, 1.09 to 1.30)); and missed school for a month due to illness (AOR: (India: 1.73, 1.49 to 2.01) and (Brazil: 1.16, 1.08 to 1.25)) was observed. CONCLUSION: Early life health, educational and economic disadvantages are associated with adult multimorbidity and appear to contribute to the later course of life. A life course approach to the prevention of multimorbidity in adulthood in LMICs may be useful in health programmes and policies.

RESUMO

Recent work in family planning has shifted from an instrumentalist perspective on quality in contraceptive counselling, which views quality as a means to encourage contraceptive uptake, to privilege quality of care as a valued end in itself. In this context of shifting narratives about quality, it is important to understand how health systems and providers navigate potential conflicts between instrumentalist definitions of quality versus a person-centred definition that considers meeting clients' contraceptive needs and preferences as an important end goal in and of itself. However, we know little about how providers and other health system stakeholders interpret the concept of quality in counselling, and how their experiences with different quality monitoring systems influence their ability to provide person-centred care. This qualitative study draws from 51 in-depth interviews with public healthcare providers and health facility administrators in Ethiopia, Mexico and India. Across all three countries, except for some cases in India, administrators were concerned with encouraging uptake of contraceptives in order to meet local and national level goals on contraceptive uptake and maternal health. In contrast, providers were more concerned with responding to client desires and needs. However, participants across all levels shared the opinion that successful counselling should end with contraceptive uptake. We conclude that the instrumentalist view of quality counselling continues to prevail across all three countries. Our findings suggest that encouraging healthcare providers and administrators to meet even relatively broad targets set by government reinforces an instrumentalist approach, as opposed to an approach that privileges person-centred care.

RESUMO

ABSTRACT Introduction: Data on the prevalence of clinically significant antigens (Rh, Kell, Kidd, Duffy, MNSs, Lewis, P and Lutheran) among the Indian donor population is sparse. Objective: This prospective study was aimed at determining the prevalence of 21 clinically significant antigens for the first time in the South Indian donor population. Method: A total of 672 regular O group blood donors were enrolled for Rh (C, c, E, e) and Kell (K) antigens typing. Of these, 188 donors were typed for other clinically significant antigens (k, Kpa, Kpb, Jka, Jkb, Fya, Fyb, M, N, S, s, P1, Lea, Leb, Lua and Lub). Results: Antigen frequencies were expressed in percentages. In our study, R1R1 and rr were the most common phenotypes among D+ and D− donors, respectively. Among the Rh antigens, the e antigen was expressed by 97.5% and 100% of D+ and D− donors, respectively. The K antigen was found in only 0.15% of donors. In the Duffy and Kidd blood group system, Fy (a+b+) and Jk (a+b+) were the most frequent phenotypes, respectively. In the MNSs blood group system, M+N+ and S−s+ were the most common phenotypes reported. The Le (a−b+) was found to be the phenotype with the highest prevalence in the Lewis blood group system. The Lu (a−b+) was the only phenotype found in the Lutheran blood group system. Conclusion: Knowledge regarding the prevalence of antigens in a given population is essential in developing cost-effective in-house panels and a rare donor registry comprising donors typed negative for a high-frequency antigen or a combination of common multiple antigens.

RESUMO

The COVID-19 pandemic has affected many daily activities, primarily as a result of the perceived contagion risk and government restrictions to mitigate the spread of the virus. To this end, drastic changes in the trip choices for commuting to work have been reported and studied, mostly through descriptive analysis. On the other hand, modeling-based research that can simultaneously understand both changes in mode choice and its frequency at an individual level has not been much used in existing studies. As such, this study aims to understand the changes in mode-choice preference and the frequency of trips, comparing pre-COVID with during-COVID scenarios, in two different countries of the Global South: Colombia and India. A hybrid multiple discrete-continuous nested extreme value model was implemented using the data obtained from online surveys in Colombia and India during the early COVID-19 period of March and April 2020. This study found that, in both countries, utility related to active modes (more used) and public transportation (less used) changed during the pandemic. In addition, this study highlights potential risks in likely unsustainable futures where there may be increased use of private vehicles such as cars and motorcycles, in both countries. It was also identified that perceptions toward government responses had a significant impact on the choices in Colombia, though this was not the case in India. These results may help decision makers focus on public policies to encourage sustainable transportation by avoiding the detrimental long-term behavioral changes resulting from the COVID-19 pandemic.
