• Pradhan Mantri Matru Vandana Yojana (PMMVY) (2016)
• Surakshit Matritva Aashwasan (SUMAN)
• Anaemia Mukt Bharat (2018)

Way Forward

To effectively mitigate the prevalence of high-risk pregnancies and promote equitable access to healthcare, the study recommends:

• Region-specific interventions targeting areas with high prevalence rates
• Strengthening antenatal care services, particularly for at-risk women
• Investing in healthcare professional training to identify and manage high-risk pregnancies
• Coordinating and integrating existing government initiatives for holistic maternal care.

Conclusion

In conclusion, the study advocates for a comprehensive approach to address the challenges posed by high-risk pregnancies, with a focus on safeguarding maternal and child health and ensuring equitable healthcare access across socio-economic strata.

1. Exploring Ultradian Rhythms: Embracing Life’s Natural Cycle

Introduction

Life on Earth exhibits a series of recurring processes vital for sustaining and improving survival, with one such cornerstone process being ultradian rhythms.

Distinct from circadian rhythms, ultradian rhythms are biological cycles occurring more frequently than once every 24 hours, governing crucial physiological functions.

Key Characteristics of Ultradian Rhythms

1. Frequency: Ultradian rhythms recur more frequently than circadian rhythms, influencing various biological processes.

2. Physiological Patterns: These rhythms regulate heartbeat, breathing, hormonal release, and brain-wave activity, ensuring proper functioning of living organisms.

Significance

• Sleep Cycle: An exemplary ultradian rhythm is the sleep cycle, comprising alternating periods of REM (Rapid Eye Movement) and non-REM sleep, typically lasting around 90 minutes each.
• REM and Non-REM Sleep: REM sleep involves dreaming, while non-REM sleep is vital for physical restoration and memory consolidation.

Role in Hormonal Regulation

1. Pulsatile Hormone Secretion: Ultradian rhythms affect the pulsatile secretion of hormones like growth hormone, cortisol, and insulin throughout the day.

2. Metabolism and Stress Response: These hormonal fluctuations play a crucial role in regulating metabolism, energy levels, and responses to stress, ensuring overall well-being.

1. What is in IPCC’s Assessment Reports?

Introduction

Since its establishment in 1988, the UN Intergovernmental Panel on Climate Change (IPCC) has played a central role in evaluating climate science and shaping worldwide responses to climate change through its assessment reports and special publications.

The recent Sixth Assessment Report (AR6) highlights the pressing need to restrict global warming to 1.5 degrees Celsius, reflecting the gravity of the situation.

Key Findings of AR6

• AR6 sends a clear and urgent warning that time is rapidly dwindling to limit global warming to 1.5 degrees Celsius.
• It emphasizes the imperative for immediate action to mitigate the adverse impacts of climate change.
• Additionally, the report highlights the considerable challenges associated with adapting to climate change and proposes strategies to bolster resilience in both natural and human-made systems.

Initiation of AR7 Cycle

• In January 2024, the IPCC launched its seventh assessment cycle (AR7) with a bureau meeting held in Turkey.
• This meeting focused on discussions regarding budget allocation, timelines, and the overall work program for the upcoming cycle.
• Insights gleaned from the AR6 cycle, coupled with contributions from member countries, informed deliberations on the structure and thematic focus of forthcoming reports.

Global Stocktake and IPCC’s Role

• The global stocktake (GST) serves as a crucial mechanism for evaluating progress toward the goals outlined in the Paris Agreement, with the IPCC playing a pivotal role by providing scientific input.
• Member countries have requested IPCC reports to align with the GST, facilitating comprehensive assessments of the effectiveness of climate action initiatives.

Scope and Timeline of AR7 Cycle

• The AR7 cycle will encompass a range of reports, including full assessment reports, synthesis reports, methodology reports, and a special report specifically addressing climate change and its impact on urban areas.
• Methodology reports will cover topics such as short-lived climate forcers and carbon removal, with technical guidelines on impacts and adaptation set to be updated.
• The publication timeline aims for special and methodology reports to be released by 2027, although timelines for assessment reports are subject to further discussion.

Challenges and Considerations

• One of the primary challenges facing the IPCC is balancing the imperative for timely reports with the rigorous review process and the evolving landscape of climate research.
• The shortened timelines may potentially compromise the scientific rigor and inclusivity of the reports.
• Additionally, limited timeframes may hinder effective engagement with marginalized communities and stakeholders, thereby impacting the overall quality of the reports.
