Background: Sarcopenia, a multifactorial disorder involving metabolic disturbance, suggests potential for metabolite biomarkers. Carnitine (CN), essential for skeletal muscle energy metabolism, may be a candidate biomarker. We investigated whether CN metabolites are biomarkers for sarcopenia. Methods: Associations between the CN metabolites identified from an animal model of sarcopenia and muscle cells and sarcopenia status were evaluated in men from an age-matched discovery (72 cases, 72 controls) and a validation (21 cases, 47 controls) cohort. Results: An association between CN metabolites and sarcopenia showed in mouse and cell studies. In the discovery cohort, plasma C5-CN levels were lower in sarcopenic men (P=0.005). C5-CN levels in men tended to be associated with handgrip strength (HGS) (P=0.098) and were significantly associated with skeletal muscle mass (P=0.003). Each standard deviation increase in C5-CN levels reduced the odds of low muscle mass (odd ratio, 0.61; 95% confidence interval [CI], 0.42 to 0.89). The area under the receiver operating characteristic curve (AUROC) of CN score using a regression equation of C5-CN levels, for sarcopenia was 0.635 (95% CI, 0.544 to 0.726). In the discovery cohort, addition of CN score to HGS significantly improved AUROC from 0.646 (95% CI, 0.575 to 0.717; HGS only) to 0.727 (95% CI, 0.643 to 0.810; P=0.006; HGS+CN score). The improvement was confirmed in the validation cohort (AUROC=0.563; 95% CI, 0.470 to 0.656 for HGS; and AUROC=0.712; 95% CI, 0.569 to 0.855 for HGS+CN score; P=0.027). Conclusion C5-CN, indicative of low muscle mass, is a potential circulating biomarker for sarcopenia in men. Further studies are required to confirm these results and explore sarcopenia-related metabolomic changes.

Somatics refers to body work and movement study that emphasize internal perception and experience. Recently, a new perspective has emerged that views somatics-based techniques as a kind of mindful movement. Somatic techniques as contemplative movement can improve emotional regulation ability through improvement of body awareness or interoception. Based on this background, the present study attempts to develop a somatics based program suitable for a group of clinical patients suffering from emotional dysregulation. This study plans to collect quantitative and qualitative data in order to clarify how interoception and the related emotional regulation ability change after the program. These findings will help to explore whether the somatics technique has potential as an emotion regulation program in the future. In addition, the results are expected to contribute to finding an alternative treatment modality for patients who have not achieved a sufficient effect with conventional psychotherapy.

Sweet’s syndrome (SS) is an autoimmune-mediated acute febrile neutrophilic dermatosis with a number of possible etiologies, including infection, malignancy, and drug reactions. In contrast to its original description, it can rarely involve extracutaneous organs, including the central nervous system, cardiovascular system, lung, liver, gastrointestinal tract, spleen, and bone. To our knowledge, there have been only three cases of SS accompanied by acute kidney injury worldwide, and this is the first report in which the patient recovered completely from acute kidney injury as well as cutaneous lesions with early steroid administration. Here, we report a case of SS with acute kidney injury in a patient with myelodysplastic syndrome (MDS) whose skin lesions and renal function recovered fully with early diagnosis and steroid therapy along with a review of the relevant literature.
