DEMAND AND SUPPLY PROJECTIONS OF PEARL MILLET IN RAJASTHAN

The present study was conducted to estimate demand and supply pattern of pearl millet in Rajasthan.  The study concluded that the demand of pearl millet for food will increase over time. In 2025, total demand of pearl millet (food) will be 2613 thousand tonnes. In 2015, it is likely to be 136 thousand tonnes in urban and 1926 thousand tonnes for rural Rajasthan. In 2020, it will be 154 thousand tonnes for urban and 2165 thousand tonnes for rural Rajasthan. In 2025, it will be 174 thousand tonnes for urban and 2439 thousand tonnes for rural Rajasthan. Demand projection for pearl millet (grain) for alternative uses indicated that demand for cattle feed (concentrates) is projected to be 2018 thousand tonnes (2020) and 2340 thousand tonnes in 2025. The demand for poultry feed industry is projected at 1406 thousand tonnes in 2025. The demand for alcohol industry is projected to be 815 thousand tonnes (2020) and 1091 thousand tonnes in 2025. The demand for seed is pegged at 24 thousand tonnes and 25 thousand tonnes in 2020 and 2025 respectively. The supply of pearl millet (grain) is projected at 5401 thousand tonnes (2015), 6469 thousand tonnes (2020) and 7759 thousand tonnes (2025). The gap between demand and supply (grain) is projected to be a surplus of 51 thousand tonnes (2015), 192 thousand tonnes (2020) and 284 thousand tonnes (2025)

Evaluation of the anti-depressant potential of metformin in conditioned defeat model in golden Syrian hamsters

Background: Depression is a prevalent mood condition that has an impact on daily functioning. Globally, depression affects 264 million people. The current pharmacotherapy of depression has a lot of shortcomings. Therefore, there is a need to explore newer therapy that alleviate the symptoms of depression. Metformin was found to possess antioxidant potential and hypothesized to decrease the levels of branched-chain amino-acids essential for tryptophan uptake (precursor for serotonin synthesis). The study was designed to validate the efficacy of metformin as an anti-depressant in conditioned defeat model in male golden Syrian hamsters using open field test (OFT), forced swim test (FST) and Serum serotonin levels. Methods: After obtaining IAEC approval, the study was carried out using 8 golden Syrian hamsters each that were randomly assigned to four groups. The disease control group received 1mL normal saline, positive control was given fluoxetine 12 mg/kg, two groups of metformin 240 mg/kg given pre-insult and post-insult. The variables assessed on every third day included OFT and FST. Following the behavioral tests, serotonin-ELISA was done. To analyse the outcomes, appropriate statistical tests were applied. Results: On standardization, the model was established to a 16-day model. Further, results highlighted a significant difference in OFT, FST and serotonin levels with the metformin group and fluoxetine compared to disease control (p<0.001). However, no significant difference was observed between the fluoxetine and metformin groups (p>0.05), signifying the comparable results. Conclusions: Metformin (240 mg/kg) alleviated the depressive symptoms by modulating both behavioral and serotonin levels

Dynamics of socio-economic factors affecting climate vulnerability and technology adoption: Evidence from Jodhpur district of Rajasthan

192-196Climate change and extreme weather fluctuations are the most threatening challenges to the farming communities especially in semi-arid tropics. The paper investigates socio-economic factors affecting vulnerability and adoption of innovations using micro-level survey data of 100 systematically selected farmers in the Jodhpur district of Rajasthan, India. The results reveal that higher income, irrigation and provision of seeds reduce climate vulnerability to a great extent. Several farm level strategies have been adopted by the farmers against climate induced stress, including change in cropping pattern, reduction in irrigation usage, use of drips and sprinklers and water conservation. In case of pearl millet cropping system, we found that adoption of wide row spacing is significantly influenced by the level of the farmer’s education, land size category, climate awareness and trainings programs. The study suggests that diversified crop sequence involving pearl millet-wheat-cluster bean-barley-onion, farmers’ adoption of suitable adaptation strategies and climate resilient technologies will improve with better awareness, education and farm governance with regard to climate change. Moreover, technologies especially indigenous ones suitable to the local contextual needs must be developed or fine-tuned and disseminated for reducing climate-induced vulnerability

Grassroots farmers’ perceptions on climate change and adaptation in arid region of Rajasthan

Understanding farmers’ perspectives to climate change and adaptation is essential in designing effective and informed strategies to combat the associated vulnerability. The study assessed farmers’ perceptions to changing climatic conditions, their impacts, adaptation measures and constraints to adaptation in Bikaner district of Rajasthan. Our results showed that farmers perceived change in the distribution of rainfall, rise in temperature, increase in frequency of heat waves and droughts in the region. Further, degradation of common property resources, uncertainty in crop yields, increased soil salinity, farm unemployment and reduction in consumption were some of the potential non-climatic impacts as perceived by the farmers. As climate adaptation measures, farmers resorted to disease/heat tolerant varieties, plant protection chemicals and water conservation techniques. Moreover, lack of access to institutional credit, poorly defined property rights, inadequate infrastructure and information gaps were some of the major barriers to climate adaptation in the region. The study provides a useful guide for identifying region-specific issues and implementable adaptation strategies. Policy actions are needed in creating awareness, improving climate information services and development of infrastructure for climate resilient farming

Achieving Surgical, Obstetric, Trauma, and Anesthesia (SOTA) care for all in South Asia

South Asia is a demographically crucial, economically aspiring, and socio-culturally diverse region in the world. The region contributes to a large burden of surgically-treatable disease conditions. A large number of people in South Asia cannot access safe and affordable surgical, obstetric, trauma, and anesthesia (SOTA) care when in need. Yet, attention to the region in Global Surgery and Global Health is limited. Here, we assess the status of SOTA care in South Asia. We summarize the evidence on SOTA care indicators and planning. Region-wide, as well as country-specific challenges are highlighted. We also discuss potential directions—initiatives and innovations—toward addressing these challenges. Local partnerships, sustained research and advocacy efforts, and politics can be aligned with evidence-based policymaking and health planning to achieve equitable SOTA care access in the South Asian region under the South Asian Association for Regional Cooperation (SAARC)

Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19

IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19. Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19. DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022). INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days. MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes. RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively). CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.
