The Impact of Severe ME/CFS on Student Learning and K-12 Educational Limitations.

Newton, Faith R·Healthcare (Basel, Switzerland)·2021

This article examines how severe ME/CFS affects children's ability to attend school and learn. Many severely ill children are confined to bed or home and cannot attend regular classes. The study suggests that schools are not providing adequate support for these students and proposes new educational approaches and resources that could help them continue learning despite their illness.

Inflammation plays a causal role in fatigue-like behavior induced by pelvic irradiation in mice.

Wolff, Brian S, Alshawi, Sarah A, Feng, Li Rebekah et al.·Brain, behavior, & immunity - health·2021

Researchers gave mice targeted radiation to the pelvis (similar to cancer treatment) and found that the mice became less active afterward—a fatigue-like behavior. They discovered that inflammation, particularly a protein called IL-6, plays a key role in causing this fatigue. When they reduced inflammation using a drug called minocycline or using mice genetically unable to trigger certain inflammatory pathways, the fatigue was reduced but not completely eliminated.

The effect of IL-2 stimulation and treatment of TRPM3 on channel co-localisation with PIP2 and NK cell function in myalgic encephalomyelitis/chronic fatigue syndrome patients.

Eaton-Fitch, Natalie, Cabanas, Hélène, du Preez, Stanley et al.·Journal of translational medicine·2021

This study looked at immune cells called NK cells in ME/CFS patients and compared them to healthy people. The researchers focused on a protein channel called TRPM3 that helps control calcium levels in cells, which may be important for immune function. They found that this channel doesn't work properly in ME/CFS patients, but when cells were stimulated with a chemical called IL-2, the NK cells from ME/CFS patients could kill viruses and abnormal cells as effectively as healthy people's cells.

Broadband electrical impedance as a novel characterization of oxidative stress in single L6 skeletal muscle cells.

Ferguson, Caroline, Pini, Niccolo, Du, Xiaotian et al.·Analytica chimica acta·2021

This study tested whether a special electrical measurement could detect damage from oxidative stress (harmful chemical reactions) in muscle cells. Researchers treated rat muscle cells with hydrogen peroxide to create oxidative stress, then measured how these stressed cells behaved electrically compared to healthy cells. The stressed cells showed distinctly different electrical patterns, suggesting this technology might one day help diagnose ME/CFS by detecting oxidative stress in patients' muscle cells.

Qualitative study of the acceptability and feasibility of acceptance and commitment therapy for adolescents with chronic fatigue syndrome.

Clery, Philippa, Starbuck, Jennifer, Laffan, Amanda et al.·BMJ paediatrics open·2021

This study asked teenagers with ME/CFS who weren't getting better, along with their parents and doctors, what they thought about a therapy called Acceptance and Commitment Therapy (ACT). Everyone interviewed thought ACT sounded like a good option because it helps people focus on what matters to them while accepting difficult thoughts and feelings, rather than trying to fight them. Most teenagers were willing to try ACT, though they worried about being randomly assigned to different treatment groups in a future study.

Experiences of Living with Severe Chronic Fatigue Syndrome/Myalgic Encephalomyelitis.

Strassheim, Victoria, Newton, Julia L, Collins, Tracy·Healthcare (Basel, Switzerland)·2021

This study listened to five people living with the most severe form of ME/CFS—those who are bedbound, housebound, or wheelchair-dependent—to understand what their daily lives are really like. By interviewing them and analyzing their stories, researchers found three main themes: how they experience living with the illness, the major challenges it creates, and how they try to manage their condition. This research helps doctors and scientists better understand the needs of the most severely affected patients.

Three Cases of Severe ME/CFS in Adults.

Williams, Leah R, Isaacson-Barash, Carol·Healthcare (Basel, Switzerland)·2021

This study describes the experiences of three adults living with ME/CFS at different severity levels—moderate, severe, and very severe. The researchers wanted to show how differently this illness affects people and how overwhelming it can be, especially for those who are housebound or bedbound. The study highlights what doctors and healthcare providers can do to better support patients with this complex condition.

[Current state about researches on selection of experimental indexs mechanisms of acupuncture underlying improvement of chronic fatigue syndrome].

Li, Yan-Hui, Ma, Qiao-Lin, Hu, Bin et al.·Zhen ci yan jiu = Acupuncture research·2021

This review examined research from the past 10 years on how acupuncture may help chronic fatigue syndrome by looking at four main body systems: immune function, stress hormones and brain chemistry, the body's ability to handle cellular damage, and cell signaling pathways. The researchers found evidence that acupuncture appears to work through multiple mechanisms rather than just one, potentially helping the body recover from CFS through different pathways.

Chronic Fatigue Syndrome and Bone Marrow Defects of the Jaw - A Case Report on Additional Dental X-Ray Diagnostics with Ultrasound.

Lechner, Johann, Schick, Fabian·International medical case reports journal·2021

This case report describes a young man with ME/CFS who had headaches and tinnitus but no visible bone problems on standard X-rays. When doctors used ultrasound imaging, they found a suspicious area in his lower jawbone. Surgery revealed a fungal infection (aspergillosis) and inflamed tissue that standard X-rays had missed. This suggests that ultrasound might be a better tool for detecting hidden bone and jaw problems in some ME/CFS patients.

mapMECFS: a portal to enhance data discovery across biological disciplines and collaborative sites.

Mathur, Ravi, Carnes, Megan U, Harding, Alexander et al.·Journal of translational medicine·2021

Researchers created mapMECFS, an online database that brings together research information about ME/CFS from scientists around the world. Instead of having data scattered across different locations and websites, this portal allows researchers to easily find, share, and compare information about the disease in one place. This tool is designed to help scientists discover patterns and connections that might reveal new ways to diagnose and treat ME/CFS.

Potential Therapeutic Benefit of Low Dose Naltrexone in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: Role of Transient Receptor Potential Melastatin 3 Ion Channels in Pathophysiology and Treatment.

Cabanas, Helene, Muraki, Katsuhiko, Eaton-Fitch, Natalie et al.·Frontiers in immunology·2021

This study investigated whether a low-dose medication called naltrexone (LDN) might help treat ME/CFS by examining how it affects immune cells called NK cells. Researchers found that NK cells from ME/CFS patients taking LDN showed restored activity in a specific ion channel (TRPM3) that had previously been impaired. This suggests LDN may help restore normal immune function in ME/CFS patients, though larger clinical trials are needed to confirm whether it actually improves symptoms.

[Imaging and Manipulation of Stem and Progenitor Cells for Revealing the Novel Mechanism of Local Tissue Maintenance in the Brain].

Kataoka, Yosky·Yakugaku zasshi : Journal of the Pharmaceutical Society of Japan·2021

This study examined special cells in the brain called glial progenitor cells that help maintain healthy brain tissue and manage inflammation. Researchers used imaging technology to track these cells and discovered that when these cells are removed, the brain develops harmful inflammation and immune activation. The findings suggest these cells may play a protective role and could be targeted to treat conditions associated with brain inflammation, including chronic fatigue syndrome.

How do women suffering from multiple chemical sensitivity experience the medical encounter? a qualitative study in Spain.

Briones-Vozmediano, Erica, Espinar-Ruiz, Eva·Disability and rehabilitation·2021

This study interviewed 22 Spanish women with Multiple Chemical Sensitivity (MCS) to understand their experiences with doctors and the healthcare system. The women reported two major problems: they cannot avoid exposure to chemicals in their environment, and they struggle to find effective treatment. Many also felt that healthcare providers didn't believe their illness was real or took their symptoms seriously.

Caring for the Patient with Severe or Very Severe Myalgic Encephalomyelitis/Chronic Fatigue Syndrome.

Montoya, Jose G, Dowell, Theresa G, Mooney, Amy E et al.·Healthcare (Basel, Switzerland)·2021

This guide focuses on caring for people with severe ME/CFS who struggle to leave their homes or beds. The authors explain that these patients often can't visit doctors' offices and doctors frequently don't have good information about how to help them. The guide provides practical recommendations for diagnosis, assessment, and treatment options, including using telemedicine and working closely with patients and caregivers to provide better care.

The Health-Promoting Properties and Clinical Applications of Rice Bran Arabinoxylan Modified with Shiitake Mushroom Enzyme-A Narrative Review.

Ooi, Soo Liang, Pak, Sok Cheon, Micalos, Peter S et al.·Molecules (Basel, Switzerland)·2021

This review examines a supplement called RBAC, made from rice bran processed with shiitake mushroom enzyme, which may have immune-boosting and anti-inflammatory effects. The authors found evidence that RBAC might help with several conditions including cancer, HIV, diabetes, irritable bowel syndrome, liver disease, and possibly chronic fatigue syndrome and the common cold. The supplement appears safe at typical doses of 2-3 grams per day, but more research is needed to confirm its benefits.

Lessons From Heat Stroke for Understanding Myalgic Encephalomyelitis/Chronic Fatigue Syndrome.

Stanculescu, Dominic, Sepúlveda, Nuno, Lim, Chin Leong et al.·Frontiers in neurology·2021

This study compares how the body breaks down during heat stroke with what happens in ME/CFS. Both conditions involve similar problems: inflammation, damage to the gut lining that allows harmful substances into the bloodstream, blood clotting issues, and problems with how cells produce energy. By understanding heat stroke better, researchers hope to find new ways to treat ME/CFS.

Split-Second Unlearning: Developing a Theory of Psychophysiological Dis-ease.

Hudson, Matt, Johnson, Mark I·Frontiers in psychology·2021

This study proposes that early emotional experiences—both traumatic and everyday—can create lasting patterns in how our bodies respond to stress. When we encounter triggers related to those memories, our body automatically activates a stress response even if the threat is no longer present. The researchers describe a new therapy approach where patients learn to observe their own automatic responses in the moment and gradually 'unlearn' the connection between the memory and the physical stress reaction.

Post-COVID-19 syndrome: epidemiology, diagnostic criteria and pathogenic mechanisms involved.

Carod-Artal, F J·Revista de neurologia·2021

Many people who have had COVID-19, even mild cases, don't fully recover and experience long-lasting symptoms for months afterward. This article reviews what we know about post-COVID-19 syndrome, including who gets it, what symptoms they have, and what might be causing it. Common symptoms include fatigue, breathing problems, difficulty concentrating, anxiety, and depression. The exact biological reasons why this happens are still unknown, though experts think abnormal immune and inflammatory responses may play a role.

Post-Acute COVID-19 Syndrome and the cardiovascular system: What is known?

Dixit, Neal M, Churchill, Austin, Nsair, Ali et al.·American heart journal plus : cardiology research and practice·2021

Some people who have had COVID-19 develop long-lasting symptoms weeks or months later, including chest pain and heart palpitations (feeling your heart racing). This review examines what we know about how COVID-19 affects the heart during this long-COVID period. While the virus itself rarely causes direct heart damage, it can trigger several heart-related conditions that may explain why patients experience these symptoms.

Potential Implications of Mammalian Transient Receptor Potential Melastatin 7 in the Pathophysiology of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: A Review.

Du Preez, Stanley, Cabanas, Helene, Staines, Donald et al.·International journal of environmental research and public health·2021

This review examines a protein called TRPM7 that may play a role in ME/CFS. TRPM7 is an ion channel—a type of gateway that controls how calcium and other minerals move in and out of cells—and it appears to affect the nervous system, immune system, heart, and metabolism. The authors suggest that problems with TRPM7 could help explain some of the complex symptoms seen in ME/CFS, though this is still a developing area of research.
