Summary: Fatigue is a common and debilitating symptom in primary Sjogren's syndrome (pSS) patients. This study aimed to evaluate fatigue and other symptoms in pSS patients and investigate if there is symptom overlap with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The severity of pSS symptoms and disease activity were assessed, and hand grip strength (HGS) and autoantibody levels were measured. Some pSS patients experienced severe fatigue and exhibited higher levels of pain, depression, and sleep disturbances. Four out of eighteen pSS patients met the criteria for ME/CFS. HGS parameters correlated strongly with fatigue severity but fully recovered after exertion, unlike ME/CFS. Elevated levels of certain autoantibodies were associated with disease activity but not fatigue severity. Only a small subgroup of pSS patients fulfilled the criteria for ME/CFS, and post-exertional malaise was primarily triggered by mental/emotional exertion rather than physical exertion. HGS assessment is an objective measure for overall fatigue severity.

Summary: The sequela of COVID-19, known as post-COVID-19 condition or syndrome (PCS), encompasses a range of symptoms caused by immune dysregulation, autoimmunity, endothelial dysfunction, viral persistence, and viral reactivation. However, it is unclear whether different clinical subgroups of PCS can be distinguished based on the expression of biomarkers. There is an overlap between symptoms and mechanisms of PCS and postinfectious myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). Currently, there are no curative therapies available for ME/CFS or PCS, but the identified mechanisms provide targets for therapeutic interventions. To accelerate the development of therapies, it is proposed to evaluate drugs targeting different mechanisms in clinical trial networks using harmonized diagnostic and outcome criteria and subgroup patients based on comprehensive clinical profiling, including diagnostic and biomarker phenotyping.

Summary: Patients diagnosed with ME/CFS showed impaired physical and mental exertion ability, worse pain, and poorer overall health compared to individuals with similar symptoms but no ME/CFS diagnosis. These results support the focus on patients' self-care, particularly in terms of energy management.

Summary: This study aimed to quantify the duration of post-exertional malaise (PEM) symptoms. Using the Symptom Severity Scale (SSS), the severity and duration of PEM symptoms in ME/CFS patients and healthy controls were assessed. The results showed a significantly prolonged recovery time in ME/CFS patients, with an average of about two weeks, compared to only two days in the control group. These data provide valuable insights for understanding and managing exercise-induced symptoms in ME/CFS patients.

Summary: ME/CFS is hypothesized to be caused by autonomic nervous system dysfunction and vascular dysregulation due to β2AdR dysfunction, resulting in excessive release of vasoconstrictors in skeletal muscles. The bioenergetic disturbance in skeletal muscle contributes to postexertional malaise, exercise intolerance, and disease chronification.

Summary: ME/CFS is a chronic debilitating disease characterized by severe fatigue, pain, sleep disruption, and cognitive dysfunction. Current treatments focus on symptom management and addressing psychological sequelae, with ongoing efforts towards identifying effective therapies and understanding the mechanistic basis of the disease.

Summary: The study revealed significant differences in the intestinal microbiota and metabolomic profile between CFS/ME patients and healthy controls, indicating characteristics of dysbiosis. Specific microbial compositions were observed in the oral and fecal samples of CFS/ME patients, along with abnormal levels of certain substances detected in the metabolomic analysis. Further research is needed to determine the causality and potential relationship between microbial changes and the onset of CFS/ME, as well as their association with secondary symptoms.

Summary: This study examined the use of high-dose AEO as a medical food to relieve pathological fatigue in ME/CFS and Long-COVID patients. The results showed significant reductions in physical and mental fatigue after 6 weeks of treatment, suggesting that AEO may be an effective treatment option.

Summary: This study proposes the use of Bayesian statistics to analyze metabolomics data and improve the assessment of specific differences. By incorporating prior information from one study into the next study, Bayesian statistics identified biological conclusions about myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) that were not found through frequentist approaches.

Summary: This review discusses the controversy surrounding the condition of ME/CFS, emphasizing the importance of historical perspective in understanding the disputed causation. It suggests that academic research rather than psychological theorization is key to proper understanding and treatment of the disease.

Summary: OZ1 is a crucial protein involved in multiple RNA editing events in the chloroplast, interacting primarily with PPR proteins through its Znf domains and unique C-terminal region. Truncation assays of OZ1 revealed the necessity of its Znf domains for restoring chloroplast RNA editing in vivo, highlighting their key role in the editing process and interaction with RNA-binding factors like ORRM1. These findings contribute to a better understanding of the chloroplast plant editosome model.

Summary: We developed a computational workflow to assemble Rubisco enzyme subunits from transcriptomics data and predicted ancestral Rubiscos of the Solanaceae family. Our findings identified superior ancestral Rubiscos with improved kinetics for C-3 plants, which have the potential to help plants adapt to anthropogenic climate change. This study also advanced our understanding of the evolution of Rubisco's catalytic traits.

Summary: Post-exertional malaise (PEM) is a prominent symptom of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). By monitoring plasma metabolites, this study found significant differences in metabolic response and recovery pattern between ME/CFS patients and healthy control participants after two maximal exercise tests. Glutamate metabolism was identified as a crucial factor in the metabolic disruptions that lead to PEM.

Summary: This study identified expanded cytotoxic CD8(+) Temra cells in the blood of patients with ICI myocarditis, which were clonally expanded and exhibited activated and cytotoxic phenotypes. These cells progressed into an exhausted phenotype after glucocorticoid treatment. The study also demonstrated the interaction between these expanded cells and innate immune cells, as well as the absence of key anti-inflammatory signals.

Summary: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a disabling multisystem illness characterized by fatigue, inflammatory symptoms, cognitive dysfunction, and post-exertional malaise. This study found that ME/CFS patients have altered fatty acid metabolism in immune cells, specifically Natural Killer cells, CD4+ T cells, and CD8+ T cells. These metabolic shifts may impact T and NK cell effector function and shed light on the mechanism of action of the illness.

Summary: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a complex disease characterized by unexplained fatigue and other symptoms. This study found increased levels of extracellular vesicles (EVs) and IL2 cytokine in plasma of ME/CFS patients. The correlations between specific proteins and clinical data suggest immune response and hemostasis dysfunctions in ME/CFS.
