📊 Nou estudi ho confirma: la continuïtat amb el mateix professional mèdic o d’infermeria redueix fins a un 30 % els ingressos hospitalaris en pacients amb atenció domiciliària 👩‍⚕️👨‍⚕️ La relació estable amb els professionals redueix la necessitat d’atenció urgent i alleugereix la pressió sobre el sistema de #salut 🔎 L’estudi del @CAPSBEsq i el #Clínic- @idibaps, publicat a Annals of Family Medicine, mostra que quan el 75 % de les visites les fa el mateix equip, també disminueix l’ús de serveis d’emergència i d’ambulàncies ℹ️f.mtr.cool/iezzbhnjqo

When Muscles Talk, Neurons Grow What happens when exercised muscle “speaks” to motor neurons? Turns out, neurons listen. Key science-backed takeaways 1. The setup Motor neurons were biochemically stimulated using conditioned media from exercised muscle, compared to controls. 2. What changed - Biochemical stimulation significantly increased: Total neurite length - Maximum neurite length - Migration area 3. When it mattered most Growth differences became strongest in the later stages of the 5-day experiment. 4. Growth speed matters Rates of neurite growth and migration were dramatically higher with stimulation (p < 0.001 to p < 0.0001). 5. Exercise vs spontaneous muscle activity Both enhanced neuron growth, but exercise-derived signals were superior, especially for: - Total neurite length - Migration area 6. Statistics check n = 6 per group, Two-Way ANOVA and t-tests, all significant (p < 0.05). Exercise doesn’t just strengthen muscles, it releases signals that actively drive motor neuron growth. Move your body. Your neurons are paying attention.

The focus on preventive neurology is indeed crucial! Moving beyond treatment to proactive strategies could significantly enhance long-term outcomes for patients.

Happy New Year! Ojalá el 2026 nos regale tiempo para leer con calma, para discutir sin gritar y para cambiar de opinión sin sentirlo como una derrota. Que la evidencia siga incomodándonos, como debe ser, y que la imaginación no se nos oxide en medio de tanta estadística. Y, sobre todo, que no perdamos el sentido del asombro: ese motor antiguo, profundamente humano, que nos empuja a hacer preguntas aunque sepamos que muchas no tendrán respuesta inmediata. Porque al final, como en la evolución, no sobrevive el que cree tener la razón, sino el que aprende a adaptarse. Salud, ciencia y un 2026 con más preguntas bien hechas que certezas mal pensadas.

How the brain talks to the immune system This diagram shows the inflammatory reflex - a neural circuit where the brain regulates inflammation through the vagus nerve. It’s how psychological stress, inflammation, and immune activity stay linked. 1️⃣ The signal starts in the brain The vagus nerve carries electrical impulses from the brainstem to the spleen, the body’s blood-filtering and immune-coordinating organ. 🟢 Example: Deep breathing and meditation can activate the vagus nerve, lowering heart rate and reducing circulating inflammatory markers like CRP and IL-6. 2️⃣ The spleen acts as a relay When the vagus nerve is stimulated, it triggers the splenic nerve to release noradrenaline, which activates immune T cells to release acetylcholine. 🟢 Example: In animal models, vagus nerve stimulation increased noradrenaline in the spleen within minutes, showing how fast the nervous system can modulate immunity. 3️⃣ Acetylcholine calms inflammation This neurotransmitter binds to receptors on macrophages, reducing the release of tumor necrosis factor-α (TNF-α), an inflammatory cytokine involved in chronic disease. 🟢 Example: Clinical studies using implanted vagus nerve stimulators in rheumatoid arthritis patients lowered TNF-α levels and improved joint pain without immunosuppressive drugs. The inflammatory reflex shows that inflammation isn’t just chemical, it’s electrical. The brain can literally tell the immune system when to stand down.

Children who have strong, consistent relationships with their grandparents often experience better emotional wellbeing and greater resilience. According to research highlighted by Harvard’s Center on the Developing Child, dependable and nurturing relationships act as a critical buffer against childhood stress. These supportive bonds help stabilize a child’s nervous system, improve emotional regulation, and strengthen healthy brain development. Grandparents frequently provide exactly this steady, caring presence. Studies have shown that children who regularly spend time with their grandparents often display lower levels of depression, healthier stress responses, stronger social skills, and greater empathy.

Physical activity is the most effective intervention available for promoting brain health and longevity. Recent research demonstrates that regular exercise, even in modest amounts, is effective for enhancing brain volume, improving memory, and reducing the risk of neurodegenerative diseases. Beyond its cognitive benefits, moderate physical activity also contributes to extended lifespan and better overall health outcomes. Even regular walking has shown to have powerful impacts on brain structure and function: *️⃣Activity levels equivalent to 4,000 steps per day have been linked to measurable increases in gray matter and white matter volumes (PMID: 38073389) *️⃣A 2011 study showed that 40 minutes of walking, three times per week lead to a 2% increase in hippocampal volume over one year, effectively reversing 1–2 years of age-related atrophy and enhancing spatial memory performance (PMID: 21282661). *️⃣A more recent study suggests that activity levels equivalent to walking just under 3 hours daily for the least active populations could extend lifespan by 11 years on average (doi: 10.1136/bjsports-2024-108125). Even walking is an accessible, non-pharmacological intervention for promoting brain health, reducing disease risk, and enhancing longevity.

Exercising Through Cancer: When Movement Becomes Medicine 1. Exercise isn’t just “supportive care” for cancer. The evidence says it can be part of treatment. 2. It may slow tumor progression by changing immune function, blood flow, and metabolism inside the tumor environment. 3. It can improve treatment response, potentially making chemo, radiation, and immunotherapy work better. 4. It’s linked to better survival in several cancer types, not just better quality of life. 5. Clinical use is still limited because studies vary a lot in type, dose, and timing of exercise. 6. We need biomarkers to predict who benefits most and what “exercise prescription” fits each case. The future of cancer care may include a new standard dose. Not only drugs, but movement too.

@OptiMindInsight Absolutely agree. When people understand the why, exercise stops being a task and becomes intentional brain training. Knowing you are improving neuroplasticity, stress regulation, and long-term cognitive resilience makes the benefits feel real and sustainable.

Exercise is a brain drug. Here’s the biology behind it New review in Frontiers in Molecular Neuroscience breaks down how exercise boosts brain BDNF, the key molecule for learning and memory. What matters most: 1. Exercise reliably increases brain BDNF, a driver of neuroplasticity and neurogenesis 2. BDNF supports memory, learning, mood, and stress resilience 3. Blocking BDNF signaling removes many cognitive benefits of exercise How exercise raises BDNF: 4) Neuronal activity increases calcium signaling and gene expression 5) Increased cerebral blood flow activates endothelial BDNF production 6) Muscle and liver release exerkines like lactate, irisin, IGF-1, and ketones that signal the brain 7) Brain BDNF comes from neurons, blood vessels, and peripheral organs working together Exercise isn’t just movement, it’s a whole body signal that rewires the brain from the inside out.

@alegre_aya Que ya previamente eran poco saludables, algo caóticos, y que quizás el ictus haya sido consecuencia de ello. Por eso, cambiar todo ello cuando en la vida de la persona no hay antecedentes, confronta algo muy profundo en el ser de esa persona, como son los valores.
