Kojima K, Ishikawa H, Watanabe S, Nosaka N, Mutoh T. A Randomized, Double-Blind, Controlled Trial Assessing If Medium-Chain Triglycerides in Combination with Moderate-Intensity Exercise Increase Muscle Strength in Healthy Middle-Aged and Older Adults. Nutrients 2023; 15:3275. [PMID: 37513691 PMCID: PMC10383836 DOI: 10.3390/nu15143275] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Revised: 07/06/2023] [Accepted: 07/19/2023] [Indexed: 07/30/2023] Open
Abstract
An adequate nutritional intake is recommended for the prevention of physical frailty and sarcopenia. In particular, medium-chain fatty acids (MCFAs) are reportedly important for muscle strength in nursing home residents. However, the effects of MCFAs on healthy adults at risk for frailty remain unknown. Hence, a randomized, placebo-controlled study was conducted to investigate the effects of 12 weeks of medium-chain triglycerides (MCTs) intake and walking on muscle mass and function in healthy, sedentary, middle-aged and older adults with a low body mass index. Three MCT intake groups with different amounts of octanoic and decanoic acid intake were compared with a control group. After 12 weeks, knee extension strength increased in all groups, with the increases in all MCT intake groups being significantly higher than those in the control group (p < 0.05). Grip strength significantly increased from baseline in the MCT 6 g/day intake group (p < 0.05). The combination of aerobic exercise and MCT intake may be effective in preventing decline in muscle strength and promoting increase in muscle strength as they can improve muscle energy production, thereby contributing to the maintenance of good health for middle-aged and older adults at high risk for frailty and sarcopenia.

Rahyussalim AJ, Zufar MLL, Kurniwati T. A holistic approach for severe flexion contracture of bilateral hip, knee, and ankle joints in a neglected patient with prolonged knee-chest positioning on extreme undernourishment: a case report and review of the literature. J Med Case Rep 2022; 16:225. [PMID: 35610728 PMCID: PMC9128234 DOI: 10.1186/s13256-022-03439-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2020] [Accepted: 03/09/2022] [Indexed: 11/30/2022] Open
Abstract
Background Flexion contracture in the lower extremity is a common finding in the patient with neuromusculoskeletal disorders. However, severe cases due to prolonged immobilization in knee–chest position are rarely established and remain underreported. This condition is associated with high morbidity and reduced quality of life, especially when it comes to neglected cases with missed injury and late presentation for adequate primary care and rehabilitative program. It remains a difficult challenge to treat, with no established treatment protocol. In addition, other factors related to psychological and socioeconomic conditions may interfere and aggravate the health state of such patients. Case presentation A 19-year-old Javanese man presented with flexion contracture of bilateral hip, knee, and ankle joints due to prolonged immobilization in knee–chest position for almost 2 years following a traffic accident and falling in the bathroom. The condition had persisted for the last 3 years due to irrecoverable condition and lack of awareness. In addition, the patient also presented with paraplegia at level L2–S1, dermatitis neglecta, multiple pressure ulcers, community-acquired pneumonia, and severe malnutrition. Prolonged and sustained passive stretching with serial plastering were performed in the patient. By the time of discharge, patient was able to move and ambulate using wheelchair. Progressive improvement of range of motion and good sitting balance were observed by 3-month follow-up. Conclusion A combination of surgery and rehabilitative care is required in the setting of severe flexion contracture. Passive prolonged stretching showed a better outcome and efficacy in the management of flexion contracture, whether the patient undergoes surgery or not. However, evaluation of residual muscle strength, changes in bone density and characteristic, and the patient’s general and comorbid conditions must always be considered when determining the best treatment of choice for each patient to achieve good outcome and result. A holistic approach with comprehensive assessment is important when treating such patients.

Abstract
Cachexia is a multifactorial condition characterized by muscle mass loss and induces metabolic dysfunction of the skeletal muscles. The preventive effects of medium-chain triglycerides (MCT) supplementation on the oxidative capacity in skeletal muscle under cachectic condition were investigated in the present study. ICR mice were randomly divided into four groups; control, lipopolysaccharide (LPS), LPS plus long-chain triglycerides (LCT) and LPS plus MCT supplementation. LCT and MCT oil were administered to the LPS + LCT and LPS + MCT groups orally (5.0 g/kg body weight/day) by a catheter for one week. Cachexia was induced in the LPS, LPS + LCT, and LPS + MCT groups via LPS injection (7.5 mg/kg body weight, i.p.) after the supplementation. LPS induced a reduction of ketone bodies concentration in blood plasma. LPS also induced a decrease in succinate dehydrogenase activity and PGC-1α expression level in tibialis anterior muscles. Meanwhile, MCT supplementation suppressed a decrease in ketone bodies concentration and succinate dehydrogenase activity. In addition, MCT supplementation increased the level of citrate synthase activity in the muscles. These results suggested the preventive effect of MCT supplementation on oxidative capacity in skeletal muscle and the involvements of ketone bodies regulation under cachectic condition.

Abstract
Triglyceride deposit cardiomyovasculopathy (TGCV), a rare cardiovascular disorder caused by genetic or acquired dysfunction of adipose triglyceride lipase (ATGL), is marked by defective intracellular lipolysis that results in excessive accumulation of triglycerides (TGs) in the myocardium and coronary arteries, leading to intractable heart failure (HF). We have developed a specific treatment for TGCV using tricaprin, a medium chain TG, as part of a governmental rare disease project in Japan. We recently reported that tricaprin diet improved cardiac TG metabolism and left ventricular function in an ATGL-knockout (KO) mouse, a mouse model for TGCV. Here, we report the effect of tricaprin on the myocardial proteome of KO mice to elucidate the mechanisms of action of tricaprin at protein expression levels. We compared proteomic changes in the hearts of KO mice fed control or tricaprin diet. Tandem mass tag-based shotgun proteomics identified 1832 proteins common to all sample groups. Whole proteomic distribution in the heart was largely up-regulated in KO mice fed control diet. When using cut-off values (>1.5 or <0.67, FDR-adjusted p value<0.01), in fact, 65 proteins were up-regulated whereas only 2 proteins were down-regulated in the hearts of KO mice fed control diet. The former included proteins assigned to "Cardiac Arrhythmia", and "Cardiac Damage" reflecting HF by a toxicity function analysis. One of the latter was Ces1d, which is known to regulate intracellular TG metabolism. These proteomic changes observed in KO mice were dramatically rescued by the tricaprin diet. These results indicated that tricaprin diet ameliorated HF in a TGCV mouse model at protein expression levels and also provided important clues to understand mechanisms for the beneficial effect of tricaprin.

Abstract
The clinical treatment of joint contracture due to immobilization remains difficult. The pathological changes of muscle tissue caused by immobilization-induced joint contracture include disuse skeletal muscle atrophy and skeletal muscle tissue fibrosis. The proteolytic pathways involved in disuse muscle atrophy include the ubiquitin-proteasome-dependent pathway, caspase system pathway, matrix metalloproteinase pathway, Ca2+-dependent pathway and autophagy-lysosomal pathway. The important biological processes involved in skeletal muscle fibrosis include intermuscular connective tissue thickening caused by transforming growth factor-β1 and an anaerobic environment within the skeletal muscle leading to the induction of hypoxia-inducible factor-1α. This article reviews the progress made in understanding the pathological processes involved in immobilization-induced muscle contracture and the currently available treatments. Understanding the mechanisms involved in immobilization-induced contracture of muscle tissue should facilitate the development of more effective treatment measures for the different mechanisms in the future.
