October 29 is World Stroke Day, established by the World Stroke Organization in 2006.

• Stroke (cerebrovascular accident): a medical emergency where blood supply to part of the brain is suddenly interrupted (ischemic stroke, 85 per cent of cases) or a blood vessel ruptures (haemorrhagic stroke, 15 per cent). Brain cells die rapidly without oxygen and glucose.
• Global burden: stroke is the second leading cause of death globally after ischaemic heart disease. It is the second leading cause of long-term disability.
• India's burden: India has approximately 18 lakh new stroke cases annually. With a younger demographic skew and high rates of hypertension and diabetes, India's stroke burden per capita is among the highest in the developing world.
• Risk factors: hypertension (the single largest modifiable risk factor); atrial fibrillation; smoking; diabetes; physical inactivity; obesity; high LDL cholesterol.
• FAST acronym (for public awareness): Face drooping, Arm weakness, Speech difficulty, Time to call emergency.
• Golden hour: thrombolytic therapy (tPA) can dissolve a clot if administered within 4.5 hours of ischaemic stroke onset. Mechanical thrombectomy can be performed up to 24 hours in selected cases.
• National Stroke Registry Programme: ICMR's registry to map stroke epidemiology across India.
• NPCDCS: the National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases and Stroke (NPCDCS) is India's government framework for addressing non-communicable diseases.

Reports in late October 2023 confirmed the delivery of India's fourth S-400 Triumf regiment from Russia.

• S-400 contract: India signed a USD 5.43 billion contract with Russia's Almaz-Antey in October 2018 for five regiments of the S-400 Triumf long-range surface-to-air missile system.
• Capabilities: can simultaneously track up to 160 targets; engage up to 80 at ranges of 40, 120, 200, and 400 km (multiple missile types). Effective against aircraft, cruise missiles, and ballistic missiles at various altitudes.
• CAATSA concern: the USA's Countering America's Adversaries Through Sanctions Act (CAATSA, 2017) imposes sanctions on entities that conduct significant defence transactions with Russia, Iran, or North Korea. The US threatened India with CAATSA sanctions; India maintained it needed the system for sovereign defence and the purchase predated CAATSA's India-specific threat.
• India's approach: India argued that its defence diversification (expanding US, Israeli, and domestic procurement) and strategic importance to the US in the Indo-Pacific (Quad membership) should qualify it for a waiver.
• CAATSA waiver: as of October 2023, the US had not formally imposed CAATSA sanctions on India, effectively granting a de facto waiver without a formal legislative waiver.
• Deployment: the first S-400 regiment is deployed in the Punjab sector (Pakistan-facing); subsequent regiments cover China-facing sectors.

The Rafah crossing, Gaza's sole border crossing with Egypt, became the focus of international attention as the only potential humanitarian aid route.

• Rafah crossing location: on the Egypt-Gaza border in the southern Sinai/Gaza strip junction. The only crossing between Gaza and a country other than Israel.
• Control: Egypt controls the Egyptian side; the Palestinian Authority (PA) has nominal control on the Gaza side, though Hamas de facto controls Gaza (since 2007).
• Strategic importance: the only route for people and goods that does not pass through Israeli-controlled crossings.
• Events in October 2023: Israel imposed a total siege (food, water, fuel, medicine blocked). The US and Egypt negotiated a limited humanitarian corridor. Aid trucks began entering in limited numbers through Rafah from late October, but volumes were far below humanitarian needs.
• UNRWA's role: UNRWA is the primary provider of food, health, and education services to Gaza's 2.3 million people. Its warehouses in northern Gaza were evacuated; southern Gaza operations were strained.
• Gaza's pre-October 7 conditions: 80 per cent of Gaza's population was dependent on humanitarian assistance; unemployment was near 45 per cent; water access was severely restricted.

The Election Commission announced elections for five state assemblies in late 2023, with polling in Rajasthan, Madhya Pradesh, Chhattisgarh, Telangana, and Mizoram starting in November.

• Scheduled dates: Chhattisgarh (two phases: November 7, 17); Mizoram (November 7); Madhya Pradesh (November 17); Rajasthan (November 25); Telangana (November 30).
• Political significance: these five state elections are considered a semi-final before the April-May 2024 Lok Sabha elections.
• Rajasthan: ruling party (Congress) faces incumbency; anti-incumbency patterns historically affect Rajasthan governments.
• Madhya Pradesh: BJP (under Shivraj Singh Chouhan) seeks a fourth consecutive term.
• Chhattisgarh: ruling party (Congress) vs BJP.
• Model Code of Conduct (MCC): once the poll schedule is announced, the MCC comes into effect, prohibiting the ruling government from announcing new schemes or making policy decisions that could influence voters.
• NOTA: None of the Above option available in all EVMs/VVPATs since the Supreme Court's 2013 ruling in People's Union for Civil Liberties v. Union of India.

PIB highlighted progress on the National Sickle Cell Anaemia Elimination Mission (2023-47) in October 2023.

• Sickle cell disease: an inherited haemoglobin disorder where abnormal sickle-shaped red blood cells cause anaemia, painful episodes (vaso-occlusive crises), and organ damage.
• India's burden: approximately 20 lakh sickle cell carriers (trait) and 1-2 lakh affected persons, concentrated in tribal populations of Madhya Pradesh, Chhattisgarh, Jharkhand, Odisha, Maharashtra, Gujarat, and Telangana.
• Mission target: test and counsel 7 crore persons in tribal areas by 2025; achieve diagnosis and treatment for all affected by 2047.
• Scheme features:
  • Point-of-care testing at health sub-centres.
  • Hydroxyurea drug distribution (reduces crises by 50 per cent).
  • Bone marrow transplant as a curative option for eligible patients.
  • Pre-marital genetic counselling.
• Union Budget 2023-24: the mission was announced in the February 2023 budget speech.
