Assessment of the efficacy and safety of a Judo exercise program in improving the quality of life among elderly patients

Objectives: Several reports have shown that Tai Chi Chuan can be an effective way to prevent falls among the elderly. However, an exercise program that can prevent injury during falls has not been reported previously. The judo technique called ukemi is used to prevent injuries. To evaluate whether a judo-based exercise program could prevent falls in the elderly, we had the participants practice ukemi as part of a therapeutic routine. The purpose of this study was to examine the clinical significance of the program and to predict its safety. Methods: From July 2016 to March 2017, we examined 53 individuals who participated in the exercise program. The individuals were divided into high (n=39) and low (n=14) movement ability groups (HMA and LMA groups, respectively), and their physical and psychological functions were evaluated using scores from the Short-Form Health Survey 36. We also collected and analyzed data from questionnaires obtained from 384 patients who participated in the program from July 2016 to July 2019. Results: The HMA group showed a significant increase in the mental component summary scores before and after the exercise program. In the LMA group, physical functioning, social functioning, and physical component summary scores were significantly improved. Of the participants surveyed, 94.8% had a high level of satisfaction, and 93.2% began accepting the exercise as a daily habit. No adverse events were observed during these exercises. Conclusion: This novel exercise program was performed safely, and positive effects were observed, especially in individuals with a low quality of life.

Sample Preparation Methods for Lipidomics Approaches Used in Studies of Obesity

Obesity is associated with alterations in the composition and amounts of lipids. Lipids have over 1.7 million representatives. Most lipid groups differ in composition, properties and chemical structure. These small molecules control various metabolic pathways, determine the metabolism of other compounds and are substrates for the syntheses of different derivatives. Recently, lipidomics has become an important branch of medical/clinical sciences similar to proteomics and genomics. Due to the much higher lipid accumulation in obese patients and many alterations in the compositions of various groups of lipids, the methods used for sample preparations for lipidomic studies of samples from obese subjects sometimes have to be modified. Appropriate sample preparation methods allow for the identification of a wide range of analytes by advanced analytical methods, including mass spectrometry. This is especially the case in studies with obese subjects, as the amounts of some lipids are much higher, others are present in trace amounts, and obese subjects have some specific alterations of the lipid profile. As a result, it is best to use a method previously tested on samples from obese subjects. However, most of these methods can be also used in healthy, nonobese subjects or patients with other dyslipidemias. This review is an overview of sample preparation methods for analysis as one of the major critical steps in the overall analytical procedure.
