Brief report: The accuracy of parents for the thoughts and feelings of their adolescent suffering from chronic fatigue: a preliminary study of empathy.

Vervoort, Tine, Crombez, Geert, Buysse, Ann et al.·Journal of pediatric psychology·2007

This study looked at whether parents of teenagers with ME/CFS could accurately understand what their child was thinking and feeling. Researchers found that parents were less able to understand their teenager's thoughts and feelings about ME/CFS itself compared to other life situations. Interestingly, teenagers thought their mothers understood them better than their fathers did, even though fathers were actually just as accurate in understanding them.

Long-chain polyunsaturated fatty acids and the pathophysiology of myalgic encephalomyelitis (chronic fatigue syndrome).

Puri, B K·Journal of clinical pathology·2007

This study proposes that ME/CFS may be linked to persistent viral infections that interfere with how the body produces certain beneficial fatty acids called long-chain polyunsaturated fatty acids. These fatty acids are important for cell membranes and immune function. The researchers suggest that supplementing with specific oils like evening primrose oil and fish oil might help bypass this block and improve symptoms.

The thoughts and methods for clinical research on acupuncture treatment of chronic fatigue syndrome.

Yao, Renmin·Journal of traditional Chinese medicine = Chung i tsa chih ying wen pan·2007

This paper presents acupuncture treatment guidelines for chronic fatigue syndrome (ME/CFS), focusing on how acupuncture might restore balance to the body's energy systems according to traditional Chinese medicine. The authors discuss important considerations like which patients are most suitable for treatment, which acupuncture points to use, and how to measure whether the treatment is working.

[Clinical features of chronic fatigue syndrome--symptoms].

Ban, Nobutaro, Saiki, Takuya, Ko, Gyoshin et al.·Nihon rinsho. Japanese journal of clinical medicine·2007

This review article summarizes the most common symptoms experienced by people with ME/CFS. The researchers identified and described the top 10 symptoms in detail, including severe fatigue, problems with memory and concentration, muscle pain, poor sleep, and headaches. Understanding these symptom patterns can help doctors recognize and diagnose ME/CFS more accurately.

[Usefulness of growth chart in children and adolescents with chronic fatigue syndrome].

Oki, Junichi, Okubo, Jun·Nihon rinsho. Japanese journal of clinical medicine·2007

This small study looked at growth charts from three young people with chronic fatigue syndrome to see if the charts could help identify what triggered their illness. The researchers found that life events—like overexercise, family stress, or infection—appeared before symptoms like extreme tiredness, nausea, and sleep problems started. While growth charts alone cannot predict who will develop ME/CFS, they may help doctors spot important life changes that happened around the time symptoms began.

E3 PreliminaryReviewPEM not requiredReview-Narrative

[Childhood chronic fatigue syndrome].

Miike, Teruhisa·Nihon rinsho. Japanese journal of clinical medicine·2007

This review discusses chronic fatigue syndrome (CFS) in children and teenagers, a serious condition affecting 3-5% of young people. Children with CFS experience extreme tiredness, sleep problems, trouble learning and remembering, and immune system issues. While routine blood tests often look normal, special testing can reveal abnormalities in how their bodies handle energy, regulate temperature, and control hormones.

Sense of effort during a fatiguing exercise protocol in chronic fatigue syndrome.

Wallman, Karen E, Sacco, Paul·Research in sports medicine (Print)·2007

This study asked whether people with ME/CFS feel more effort when doing physical tasks compared to healthy people. Researchers had both groups perform a repetitive arm exercise for 45 minutes while rating how hard it felt. People with ME/CFS reported significantly higher effort levels and produced more force than controls, even though the task was the same for everyone.

Post-Exertional Malaise

E3 PreliminaryBehavioralPEM not requiredObservational

Orthostatic panic attacks among Vietnamese refugees.

Hinton, Devon E, Hinton, Ladson, Tran, Minh et al.·Transcultural psychiatry·2007

This study looked at Vietnamese refugees who experienced panic attacks triggered by standing up quickly from a sitting or lying position (orthostatic dizziness). The researchers found that these panic attacks were common among this group and were often linked to trauma memories and cultural beliefs about health. The study suggests that doctors treating Vietnamese refugees should check for and treat these specific panic attacks as part of their care.

[Cirrhotic cardiomyopathy].

Osipenko, M F, Bikbulatova, E A·Klinicheskaia meditsina·2007

This review examines how liver cirrhosis (severe liver disease) affects the heart. The study found that patients with cirrhosis develop heart problems including thickened heart walls and weakened heart function, especially during physical activity. These heart changes may contribute to fatigue and reduced ability to work, but importantly, these problems can improve significantly after a liver transplant.

Post-Exertional Malaise

E3 PreliminaryReviewPEM not requiredReview-Narrative

[Overview of psychiatric therapy for chronic fatigue syndrome].

Yamadera, Wataru, Itoh, Hiroshi·Nihon rinsho. Japanese journal of clinical medicine·2007

This review examines how talking therapies, particularly cognitive behavioral therapy (CBT), can help people with ME/CFS. CBT focuses on identifying unhelpful thinking patterns and behaviors—like perfectionism, avoidance, and constantly searching for physical causes—that may be making fatigue worse. The approach involves keeping steady activity levels and making small, planned increases over time, rather than pushing hard and then collapsing.

E3 PreliminaryCohortPEM not requiredCase-Control

Successful use of a primary care practice-specialty collaboration in the care of an adolescent with chronic fatigue syndrome.

Kuo, Dennis Z, Cheng, Tina L, Rowe, Peter C·Pediatrics·2007

This case report describes how one teenager with ME/CFS improved significantly when their regular doctor and a specialized ME/CFS expert worked together as a team, even though they lived in different cities. By staying in regular contact through phone calls and emails and clearly dividing responsibilities, the two doctors were able to manage the teen's symptoms more effectively. The study suggests that this type of teamwork between primary care doctors and specialists can help young people with ME/CFS get better care.

The chronic fatigue syndrome: a comparative pathway analysis.

Emmert-Streib, Frank·Journal of computational biology : a journal of computational molecular cell biology·2007

This study developed a new method to find biological pathways that go wrong in ME/CFS, rather than just looking at individual genes. The researchers compared how biological systems work differently in sick versus healthy people using computer analysis of gene expression data. This approach helps scientists understand ME/CFS as a disease of interconnected biological processes.

The hypothalamo-pituitary-adrenal axis in chronic fatigue syndrome and fibromyalgia syndrome.

Tanriverdi, F, Karaca, Z, Unluhizarci, K et al.·Stress (Amsterdam, Netherlands)·2007

This review examines how the stress response system (called the HPA axis) works differently in people with ME/CFS and fibromyalgia. The HPA axis is normally responsible for managing how your body responds to stress. Most studies show that in these conditions, the system is underactive and produces lower levels of cortisol (a stress hormone), though some studies have found different results.

An 'overwhelming illness': women's experiences of learning to live with chronic fatigue syndrome/myalgic encephalomyelitis.

Edwards, Catherine R, Thompson, Andrew R, Blair, Alan·Journal of health psychology·2007

This study interviewed eight women with ME/CFS about how they learned to cope with their illness. Many felt overwhelmed at first and frustrated when doctors didn't believe or help them. Over time, women found ways to manage by learning more about their condition, getting support from others, and taking charge of their own care, which helped them feel more in control.

[Gamma-aminobutyric acid--metabolism and its disorders].

Kowalski, Antoni, Rebas, Elzbieta, Zylińska, Ludmiła·Postepy biochemii·2007

Your brain uses a chemical messenger called GABA to calm nerve signals and prevent them from becoming overactive. When three key enzymes that control GABA levels don't work properly, it can cause various neurological problems including chronic fatigue syndrome, anxiety, seizures, and stiff-person syndrome. This article reviews what happens when GABA metabolism breaks down and how it affects the nervous system.

[Identification and application of marker genes for differential diagnosis of chronic fatigue syndrome].

Kawai, Tomoko, Rokutan, Kazuhito·Nihon rinsho. Japanese journal of clinical medicine·2007

This study looked for genetic markers (differences in how genes are expressed) that could help doctors diagnose ME/CFS with a blood test. The researchers identified 9 genes that were expressed differently in ME/CFS patients compared to healthy people, and showed these genes could potentially be used to distinguish ME/CFS from other conditions.

Definitions and aetiology of myalgic encephalomyelitis: how the Canadian consensus clinical definition of myalgic encephalomyelitis works.

Carruthers, B M·Journal of clinical pathology·2007

This article discusses how doctors should define and diagnose ME/CFS, emphasizing that clear, consistent definitions help doctors recognize the condition and understand how severely it affects individual patients. The authors argue that good clinical guidelines are essential so doctors can properly diagnose ME/CFS, predict how it will progress, and develop appropriate treatments. They stress that combining what doctors learn from individual patients with scientific research findings creates the best foundation for patient care.

Mitochondrial dysfunction and molecular pathways of disease.

Pieczenik, Steve R, Neustadt, John·Experimental and molecular pathology·2007

This article explains that many different diseases—including chronic fatigue syndrome—may share a common problem: damage to mitochondria, the energy-producing parts of our cells. When mitochondria don't work properly, they produce harmful molecules called reactive oxygen species that can further damage cells. The authors suggest that antioxidant treatments and specific urine tests might help doctors treat these conditions more effectively.

Lymphatic drainage of the neuraxis in chronic fatigue syndrome: a hypothetical model for the cranial rhythmic impulse.

Perrin, Raymond N·The Journal of the American Osteopathic Association·2007

This study proposes that ME/CFS may be connected to problems with how fluid drains from the brain and spinal cord. The author suggests that the cranial rhythmic impulse—a subtle body rhythm that practitioners can feel—reflects cerebrospinal fluid drainage and lymphatic system activity controlled by the nervous system. When this drainage process becomes disrupted, the author argues it could cause the fatigue and other symptoms of ME/CFS.

Current research priorities in chronic fatigue syndrome/myalgic encephalomyelitis: disease mechanisms, a diagnostic test and specific treatments.

Kerr, J R, Christian, P, Hodgetts, A et al.·Journal of clinical pathology·2007

This review describes an organized effort by researchers to better understand ME/CFS by studying genes and immune system changes in patients' blood. The goal is to find biological markers that can reliably diagnose the illness and to test new treatments that might help. Researchers are using advanced technology to look at thousands of genes at once to find patterns specific to ME/CFS.
