Elevated circulating follicle stimulating hormone level is associated with dyslipidemia in male type 2 diabetes mellitus patients: A cross-sectional study

Association between sarcopenia and the foot-ankle function in type 2 diabetic foot ulcer

BACKGROUND

The diabetic foot (DF) ulcer is the severe complication of type 2 diabetes mellitus (T2DM). Sarcopenia is characterized as the loss of muscle mass and strength, resulting in the increased risk of fracture and physical disability. Sarcopenia may affect the foot-ankle function in DF ulcer patients, compromise the quality of life.

OBJECTIVE

The aim was to clarify the effect of sarcopenia on foot-ankle function in patients with DF ulcer.

METHODS

In total of 108 T2DM patients with DF ulcer were enrolled. Based on the examination of muscle mass by dual energy X-ray absorptiometry (DXA) and grip strength and 5x sit-to-stand test, the DF patients were divided into sarcopenia and non-sarcopenia groups. The severity of DF ulcer was evaluated by Wagner classification. The foot-ankle function was evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score.

RESULTS

DF patients with sarcopenia showed advanced age, lower BMI, longer duration of T2DM, and more severe Wagner classification, reduced appendicular skeletal muscle mass index (ASMI), grip strength, transcutaneous oxygenpressure (TcPO2) and prolonged time of 5X sit-to-stand test. The stratified comparison analysis indicated that severity of sarcopenia and DF ulcer, reduced TcPO2, and grip strength were aggravated with the impaired foot-ankle function (P < 0.05). Multivariate Logistic analysis showed that age, TcPO2, and severe sarcopenia were risk factors deteriorating the foot-ankle function.

CONCLUSION

The sarcopenia is a key risk factor of decreasing foot-ankle function in patients with DF ulcer. Thus, the prevention of muscle mass and strength loss could be considered as part of comprehensive therapy for DF ulcer.

Lipoprotein alterations in endocrine disorders - a review of the recent developments in the field

Dyslipidemia is one of the most common disorders worldwide, which, if left untreated, results in a multitude of complications. Thus proper diagnostics, which includes identifying of secondary causes of dyslipidemia is crucial. Endocrine disorders are an important cause of secondary dyslipidemia. This paper aims to review the publications on lipoprotein alterations in endocrine disorders from the past two years and provide an overview of the recent discoveries in this dynamically developing and large field. Significant changes in lipoprotein serum concentrations are present in most endocrinological diseases and can be modified with proper treatment. Some lipoproteins have also been proposed as markers in some endocrine diseases, e.g., thyroid carcinoma. From the scope of endocrine disorders, the largest number of studies explored the lipoprotein changes in polycystic ovary syndrome and in women during the menopausal and peri-menopausal period. Even though the association of thyroid disorders with dyslipidemia is already well studied, new research has delivered some exciting findings about lipoprotein alterations in euthyroid patients with either positive antithyroid peroxidase antibodies or reduced sensitivity to thyroid hormones. The problem of the adverse metabolic profile, including dyslipidemia in hypoprolactinemia has been recognized. Moreover, this review describes other significant discoveries encompassing lipoprotein alterations in disorders of the adrenals, thyroid, parathyroid glands, pituitary, and gonads. The up-to-date knowledge of the influence of endocrine disorders and hormonal changes on serum lipoproteins is prudent as it can significantly impact therapeutic decisions.
