Ukraine

Russia’s Spring-Summer 2026 offensive has begun, with battalion-sized mechanized assaults launching against the Lyman-Borivka sector of the northern Fortress Belt on March 19. Early results favor Ukraine: the attacks are incurring heavy losses (970 killed/wounded daily, 8,000+ in the past week) without confirmed territorial gains. Critically, Ukrainian counterattacks in the Hulyaipole and Oleksandrivka directions are forcing Russia to redeploy elite VDV and naval infantry units from Donetsk Oblast southward — disrupting offensive planning and stretching already strained manpower. Russian milbloggers continue to dispute the MoD’s claim that Kupyansk has been seized; it remains contested. Ukrainian forces advanced in eastern Kostyantynivka along the T-0504 highway.

Deep strikes continue to degrade Russian capabilities: 26 air defense systems destroyed in March so far, oil refineries in Saratov and Bashkortostan burning, and a Baltic port fuel facility hit overnight. (Also covered in World)

Russia will deploy mobilized personnel from Crimea starting April 1 — a sign of recruitment struggles. Meanwhile, Ukrainian drone expertise is yielding diplomatic dividends: Zelensky confirmed Ukraine is helping five countries counter Iranian drones, with Ukrainian units scoring their first Shahed kills in the Middle East. The US contracted an additional $6.8 billion in weapons under USAI, while rejecting a Russian offer to halt intelligence sharing with Iran in exchange for ending Ukraine aid.

Investigations & Geopolitics

• The Battlefield is the Next Betting Market (War on the Rocks) — Jonathan Walberg argues prediction markets on geopolitical events have evolved beyond forecasting tools into strategic instruments that can shape crisis dynamics.

• Trump’s Visit to China Won’t Fix Much, If It Even Happens (War on the Rocks) — Daniel Rechtschaffen argues Trump’s planned state visit to China will provide only temporary stabilization. Despite recent tariff cuts and good-faith measures, “deep mutual mistrust built up over the last decade” remains unaddressed.

• Iran reportedly scales back strikes on Saudi Arabia over fear of retaliation (Jerusalem Post) — Iran has limited attacks on Saudi Arabia after assessing that targeting civilian infrastructure — electricity and desalination — would trigger direct Saudi military response. Since the war began, Iran has launched over 430 missiles and drones at Saudi targets. Iran has decided to spare Qatar while continuing operations against Kuwait, Bahrain, and the UAE.

• Patriot missile involved in Bahrain blast likely US-operated, analysis finds (Reuters) — Reuters investigation analyzing evidence suggesting the Patriot missile was US-operated rather than belonging to Bahrain’s own defense systems.

Long COVID Research

Takeaways

• Single-cell analysis reveals distinct immune signatures in Long COVID with ME/CFS — A new Frontiers study (Elahi et al) maps the specific immune remodeling: marked reduction in naive CD4+/CD8+ T cells, regulatory T cells, MAIT cells, and gamma-delta T cells, plus NK cell dysfunction. The Galectin-9–TIM-3 pathway is identified as driving gamma-delta and MAIT cell depletion. Critically, this pattern differs from idiopathic ME/CFS, which shows less pronounced alterations and no T cell exhaustion — suggesting distinct pathophysiology despite symptom overlap.

• LDN mechanism clarified: restores TRPM3 ion channel function in NK cells. Australian research shows LDN (3–4.5 mg daily) restores calcium signaling to healthy control levels via mu-opioid receptor antagonism. This provides mechanistic support for LDN’s clinical benefit in Long COVID and explains why NK cell dysfunction could be addressable.

• Long COVID after mild infection involves a distinct monocyte transcriptional state. Nature Immunology identifies LC-Mo, a monocyte phenotype with TGFβ and WNT–β-catenin signaling that correlates with fatigue severity. This pathway differs from LC after severe acute COVID — the disease isn’t one thing even within LC.

• RECOVER-AUTONOMIC ivabradine results drop March 28. Still the most anticipated near-term result for POTS-predominant LC. If positive, it would validate heart rate control as a treatment target.

• RECOVER-NEURO cognitive treatments: no clear winner. Non-drug treatments for brain fog showed small improvements across the board, but no intervention significantly outperformed others. Negative result but narrows the search space.

Directly Relevant

• Single-cell analysis reveals immune remodeling in Long COVID with ME/CFS (Frontiers in Immunology, 2026) — Single-cell RNA sequencing at 12 months post-infection comparing LC-ME/CFS vs recovered individuals. Marked reduction in naive CD8+ T cells, expansion of effector T cells, NK cell reduced frequency with impaired cytotoxic function. The Galectin-9–TIM-3 interaction is proposed as driving gamma-delta and MAIT cell depletion. Plasma Galectin-9 elevated in LC-ME/CFS. Notably, idiopathic ME/CFS showed less pronounced immune alterations with no reduction in MAIT or NK cells and no T cell exhaustion — mechanistically distinct.

• LDN restores TRPM3 ion channel function in NK cells (Frontiers in Molecular Biosciences, 2025) — Whole-cell patch-clamp electrophysiology shows LDN-treated Long COVID patients had TRPM3 current amplitudes statistically equivalent to healthy controls. Mechanism: naltrexone antagonizes mu-opioid receptors, preventing Gβγ protein subunits from blocking TRPM3 channels. Untreated LC patients showed 0% sensitivity to ononetin antagonism (severely impaired); LDN-treated showed 62.3% (matching healthy controls at 64.1%).

• Immunologically distinct Long COVID after mild acute disease (Nature Immunology, 2026) — Identifies LC-Mo, a circulating monocyte transcriptional state enriched in individuals with mild–moderate acute infection. LC-Mo shows TGFβ and WNT–β-catenin signaling and correlates with fatigue severity. Accompanied by persistent elevation of plasma CCL2, CXCL11, and TNF. Important because it distinguishes LC after mild infection from LC after severe acute COVID — different pathobiological pathways.

Significant Developments

• RECOVER March 2026 Update (RECOVER, 2026-03) — 9 new peer-reviewed publications. Key findings: adolescents vaccinated within 6 months before infection were ~1/3 less likely to develop LC; Long COVID involves activation of proinflammatory and immune exhaustion pathways; RECOVER-NEURO cognitive treatment trial showed small improvements but no treatment significantly outperformed others. RECOVER-AUTONOMIC ivabradine results will be presented at ACC on March 28.

• T cell dynamics in Long COVID recovery (International Journal of Molecular Sciences, 2026) — Study of 231 blood samples tracking CD4+ and CD8+ subpopulations and TREC levels. Long COVID patients showed ~2-fold increased effector-memory and terminal-effector CD8+ T cells with decreased naive CD8+ T cells. Soluble markers sCD25, sTIM-3, and sLAG-3 associated with symptom persistence.

• PEM mechanism: microvascular and immunometabolic interactions (Infection, 2024-2025) — Framework for understanding PEM: reduced systemic oxygen extraction and oxidative phosphorylation mediated by mitochondrial dysfunction and microcirculation impairment. Proposes reconceptualizing PEM as impaired physiological recovery rather than purely subjective.

• APTA Therapeutics acquires rovunaptabin (BC007) (APTA Therapeutics, 2025-2026) — APTA Therapeutics, led by former Berlin Cures CEO Oliver von Stein, has acquired BC007 to continue clinical development. Given maxed GPCR autoantibodies in some LC patients, this remains the most directly mechanism-targeted therapy.
