Dietary intake and physical activity in Japanese patients with type 2 diabetes: the Japan Diabetes Complication and its Prevention prospective study (JDCP study 8).

Medical nutrition therapy and exercise therapy are the cornerstones of treatment for patients with type 2 diabetes; however, there has not been a nationwide study on the actual dietary intake and physical activity status of patients since the 2000s. We aimed to clarify this in Japanese patients with type 2 diabetes using data from the Japan Diabetes Complication and its Prevention prospective (JDCP), a nationwide study launched in 2007. A total of 1992 patients with type 2 diabetes, aged 40-75 years, completed either the Brief-type, self-administered Diet History Questionnaire (1643 patients) or International Physical Activity Questionnaire (1834 patients), and their data were analyzed in this study.

Relationship between adiponectin and intramuscular fat content determined by ultrasonography in older adults.

Age-associated intramuscular adipose tissue (IntraMAT) deposition induces the development of insulin resistance and metabolic syndrome. However, the relationship between IntraMAT and biochemical parameters in older adults remains unclear. The purpose of this study, therefore, was to elucidate the relationship between adiponectin and echo intensity-estimated IntraMAT using ultrasonography in normal-weight older adults (men 9, women 13) and examine biochemical parameters.

Effect of Treatment With Sodium-Glucose Cotransporter 2 Inhibitor on the Initiation of Continuous Positive Airway Pressure Therapy in Type 2 Diabetic Patients With Obstructive Sleep Apnea Syndrome.

Background: Obese patients with type 2 diabetes mellitus often develop obstructive sleep apnea syndrome (OSAS). In this study, continuous positive airway pressure (CPAP) was initiated in Japanese patients with type 2 diabetes mellitus who developed OSAS during treatment with a sodium-glucose cotransporter 2 (SGLT2) inhibitor, and the effect of the SGLT2 inhibitor therapy on the patients was investigated.

Methods: The study was conducted in outpatients with type 2 diabetes mellitus with serum hemoglobin A1c (HbA1c) values of ≥ 6.

Relationship between physical activity time and intramuscular adipose tissue content of the thigh muscle groups of younger and older men.

We investigated the effect of physical activity on muscle tissue size and intramuscular adipose tissue (IntraMAT) content in the thigh muscle groups of younger and older men. Twenty younger and 20 older men participated in this study. The muscle tissue cross-sectional area (CSA) and the IntraMAT content in the quadriceps femoris (QF), hamstrings (HM), hip adductors (AD), and mid-thigh total were measured using magnetic resonance imaging.

Investigation of d-allulose effects on high-sucrose diet-induced insulin resistance via hyperinsulinemic-euglycemic clamps in rats.

d-Allulose, a C-3 epimer of d-fructose, is a rare sugar that has no calories. Although d-allulose has been reported to have several health benefits, such as anti-obesity and anti-diabetic effects, there have been no reports evaluating the effects of d-allulose on insulin resistance using a hyperinsulinemic-euglycemic clamp (HE-clamp). Therefore, we investigated the effects of d-allulose on a high-sucrose diet (HSD)-induced insulin resistance model.

Effect of electromyostimulation on intramyocellular lipids of the vastus lateralis in older adults: a randomized controlled trial.

Background: Excessive intramyocellular lipid (IMCL) accumulation is a primary cause of skeletal muscle insulin resistance, especially in older adults, and interventions that reduce IMCL contents are important to improve insulin sensitivity. Electromyostimulation (EMS)-induced changes in IMCL content in older adults remain unknown. The purpose of this study was to clarify the effects of a single bout of EMS on the IMCL content of the vastus lateralis muscle in older adults.

Effects of Concomitant Administration of Sodium Glucose Co-transporter 2 Inhibitor with Insulin on Hemoglobin A1c, Body Mass Index and Serum Lipid Profile in Japanese Type 2 Diabetic Patients.

In patients with type 2 diabetes mellitus who show suboptimal blood glucose control under insulin therapy alone, concomitant treatment with an additional hypoglycemic agent that differs in its mechanism of action from insulin may be considered. We conducted this clinical trial to explore whether further control of increased blood glucose level can be achieved with concomitant use of sodium glucose co-transporter 2 (SGLT2) inhibitor as concomitant with other hypoglycemic therapy, as compared to SGLT2 inhibitor monotherapy, in patients with type 2 diabetes mellitus showing decrease in blood glucose level but less than the effect of insulin monotherapy and there was no significant differences. In the SGLT2 inhibitor monotherapy group, decreases of the serum hemoglobin A1c (HbA1c) level, body weight, body mass index (BMI) and serum triglyceride, and elevation of the serum high density lipoprotein cholesterol concentration were observed as compared to the baseline values.

Effects of Concomitant Administration of a Dipeptidyl Peptidase-4 Inhibitor in Japanese Patients with Type 2 Diabetes Showing Relatively Good Glycemic Control Under Treatment with a Sodium Glucose Co-Transporter 2 Inhibitor.

We conducted this study to determine whether additional administration of a dipeptidyl peptidase-4 (DPP-4) inhibitor might provide further improvement of the glycemic control in Japanese type 2 diabetes patients showing relatively good glycemic control under treatment with a sodium glucose co-transporter 2 (SGLT2) inhibitor. Five SGLT2 inhibitor (luseogliflozin, dapagliflozin, tofogliflozin, empagliflozin and canagliflozin) preparations and five DPP-4 inhibitor (sitagliptin, vildagliptin, alogliptin, anagliptin and linagliptin) preparations were used. The results showed that monotherapy with SGLT2 inhibitor produced significant decreases of the body weight and BMI, hemoglobin A1c (HbA1c) also decreased, but not to a significant extent.

Effects of post-fracture non-weight-bearing immobilization on muscle atrophy, intramuscular and intermuscular adipose tissues in the thigh and calf.

Objective: Disuse and/or a non-weight-bearing condition changes muscle composition, with decreased skeletal muscle tissue and increased fat within (intramuscular adipose tissue, IntraMAT) and between (intermuscular adipose tissue, InterMAT) given muscles. Excessive adipose tissue contributes to dysfunctional and metabolically impaired muscle. How these adipose tissues change during orthopedic treatment (e.

Muscle quality characteristics of muscles in the thigh, upper arm and lower back in elderly men and women.

Purpose: The ratio of fat within skeletal muscle is an important parameter that is indicative of muscle quality, and can be assessed using ultrasonography to measure echo intensity (EI). Muscle EI indicates muscle strength and risk of physical dysfunction; however, this observation was determined following examinations of only selected muscle. The purpose of this study was to investigate the EI characteristics of muscles in several regions in elderly men and women, using physical function tests and serum cholesterol levels.

Effect of 12-month resistance and endurance training on quality, quantity, and function of skeletal muscle in older adults requiring long-term care.

Older adults requiring long-term care will experience age-associated deterioration of the quality and quantity of skeletal muscle if no interventions are performed. Long-term training is considered a typical intervention method and is effective for improvement of both muscle quantity and physical function. However, how such training affects muscle quality [i.

Three-dimensional comparison of intramuscular fat content between young and old adults.

Background: Fat infiltration within skeletal muscle is known as intramuscular fat (IMF), which increases with aging. Studies have assessed IMF content, using the mid-thigh as a representative location. However, three-dimensional IMF distribution is not well understood.

Anti-pituitary antibodies against corticotrophs in IgG4-related hypophysitis.

Purpose: IgG4-related disease is a systemic inflammatory disease characterized by infiltration of IgG4-positive plasma cells into multiple organs, including the pituitary gland. Autoimmunity is thought to be involved in the pathogenesis of IgG4-related disease. The diagnosis of IgG4-related hypophysitis (IgG4-RH) is difficult because its clinical features, such as pituitary swelling and hypopituitarism, are similar to those of other pituitary diseases, including lymphocytic hypophysitis and sellar/suprasellar tumors.

Associations of intramyocellular lipid in vastus lateralis and biceps femoris with blood free fatty acid and muscle strength differ between young and elderly adults.

The present study aimed to determine relationships between intramyocellular lipid and biochemical profiles or muscle strength in elderly (n = 15; mean age, 71 years) and young (n = 15; mean age, 21 years) male and female adults. Levels of intramyocellular lipid in the vastus lateralis and biceps femoris muscles were determined using H-magnetic resonance spectroscopy. Fasting blood samples were collected to measure levels of glucose, insulin, haemoglobin A1c, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, free fatty acid, triglyceride, adiponectin, and high-sensitivity C-reactive protein.
