Article Synopsis
  • This study explored the impact of nutritional guidance centered on leucine intake versus general nutritional advice on cardiac rehabilitation patients regarding plasma leucine levels, lean body mass, and muscle strength.
  • After six months, only the intervention group had significant increases in protein and leucine intake, and there was a noticeable rise in lean body mass compared to the control group.
  • The results suggest that enhanced leucine concentration through targeted nutritional guidance can positively affect lean body mass and grip strength in patients, without requiring more intensive training.

Article Synopsis
  • Young adults with dilated cardiomyopathy (DCM) experience significant health-related quality of life (HR-QOL) issues due to their condition and typical life stressors, such as career and relationship building.
  • A case study of a 26-year-old man in a cardiac rehabilitation program showed improved exercise capacity and some HR-QOL improvements, but many emotional and social factors remained unchanged.
  • The importance of addressing both physical and psychosocial aspects in young patients with DCM was emphasized, highlighting the need for comprehensive care that includes counseling and support during rehabilitation.

Background: Malnutrition impairs quality of life and prognosis of patients with cardiovascular disease. The Mini Nutritional Assessment (MNA) is a screening tool developed for the nutritional assessment of older adults. However, usefulness of MNA for patients undergoing cardiac rehabilitation (CR) has not been fully investigated.

Frailty is an important prognostic factor in patients with cardiovascular diseases (CVD), and patients with CVD have a high rate of concurrent psycho-emotional stress, as well as depressive mood and anxiety symptoms. Despite this, few reports have examined the effects of the efficacy of Phase II cardiac rehabilitation (CR) in frail patients, including improvements in anxiety levels. In all, 137 patients (mean [±SD] age 65.

Background: Although obesity-related type 2 diabetes mellitus (T2DM) and sarcopenia in the elderly have been increasing worldwide, the associations among visceral fat accumulation, skeletal muscle indices (mass, strength, and quality) and cardiovascular diseases in T2DM remain poorly investigated.

Methods: We enrolled 183 Japanese T2DM inpatients (126 men, 57 women; mean age 64.7 ± 12.

Background & Aims: The transient receptor potential ankyrin 1 (TRPA1) channel is highly expressed in the intestinal lamina propria, but its contribution to gut physiology/pathophysiology is unclear. Here, we evaluated the function of myofibroblast TRPA1 channels in intestinal remodeling.

Methods: An intestinal myofibroblast cell line (InMyoFibs) was stimulated by transforming growth factor-β1 to induce in vitro fibrosis.

Intestinal fibrosis is an intractable complication of Crohn's disease (CD), and, when occurring excessively, causes severe intestinal obstruction that often necessitates surgical resection. The fibrosis is characterized by an imbalance in the turnover of extracellular matrix (ECM) components, where intestinal fibroblasts/myofibroblasts play active roles in ECM production, fibrogenesis and tissue remodeling, which eventually leads to the formation of stenotic lesions. There is however a great paucity of knowledge about how intestinal fibrosis initiates and progresses, which hampers the development of effective pharmacotherapies against CD.

We report here a 70 year-old male on maintenance hemodialysis who presented non-paralytic pontine exotropia. Brain MRI showed new right pons infarct. Transthoracic and transesophageal echocardiography revealed a mobile calcification at posterior mitral leaflet with rapid growing compared to 14 days ago.

Reactions of [Ni(tren)(H(2)O)(2)]X(2) (tren = tris(2-aminoethyl)amine; X = Cl (1a), Br (1b); X(2) = SO(4) (1c)) with mannose-type aldoses, having a 2,3-cis configuration (D-mannose and L-rhamnose), afforded {bis(N-aldosyl-2-aminoethyl)(2-aminoethyl)amine}nickel(II) complexes, [Ni(N,N'-(aldosyl)(2)-tren)]X(2) (aldosyl = D-mannosyl, X = Cl (2a), Br (2b), X(2) = SO(4) (2c); aldosyl = L-rhamnosyl, X(2) = SO(4) (3c)). The structure of 1c was confirmed by X-ray crystallography to be a mononuclear [Ni(II)N(4)O(2)] complex with the tren acting as a tetradentate ligand (1c.2H(2)O: orthorhombic, Pbca, a = 15.
