Sarcopenia, the loss of skeletal muscle mass and function that occurs with aging, is associated with increased risk for several adverse health outcomes, including frailty, disability, falls, loss of independent living, and mortality. At present, no pharmacological treatment exists that is able to definitely halt the progression of sarcopenia. Likewise, no(More)
BACKGROUND Pelvic recurrent rectal cancer is still a challenging clinical problem, and patients generally have a dismal prognosis and a poor quality of life. Surgical resection represents the only potentially curative treatment; neoadjuvant treatments are presently being taken into consideration to increase the resectability rate and to improve long-term(More)
BACKGROUND The role ofparathyroid glands (PTG) ultrasonography (US) in hemodialysis patients with secondary hyperparathyroidism (SHPT) is still controversial. The present study aimed at evaluating the relationship between US findings and SHPT degree as well as therapeutic outcome. METHODS Twenty hemodialysis patients with moderate SHPT and 15 with severe(More)
Cancer cachexia is characterized by skeletal muscle wasting that is mainly supported by hypercatabolism. Muscle atrophy has been suggested to depend on impaired IGF-1 signal transduction pathway. The present study has been aimed at investigating the IGF-1 system in rats bearing the AH-130 hepatoma, a well-characterized model of cachexia. IGF-1 mRNA(More)
BACKGROUND AND OBJECTIVES Bacterial-derived DNA fragments (BDNAs) have been shown to be present in dialysis fluid, to pass through dialyzer membranes, and to induce IL-6 (IL-6) in mononuclear cells. The present study aimed at assessing the eventual presence of BDNAs in the blood of hemodialysis (HD) patients and if this is associated with markers of chronic(More)
BACKGROUND The objective of the current study was to evaluate the ability of serum thyroglobulin mRNA assay in detecting local and distant recurrences in patients who underwent surgery for thyroid carcinoma. METHODS Sixty-six consecutive patients were studied. One year after surgery, all patients underwent clinical examination and radioiodine scan, and a(More)
OBJECTIVE To investigate the state of activation of the ATP-ubiquitin-dependent proteolytic system in the skeletal muscle of gastric cancer patients. SUMMARY BACKGROUND DATA Muscle wasting in experimental cancer cachexia is frequently associated with hyperactivation of the ATP-dependent ubiquitin-proteasome proteolytic system. Increased muscle ubiquitin(More)
BACKGROUND Cinacalcet is a new effective treatment of secondary hyperparathyroidism (SHPT) in hemodialysis patients (HP), but the alterations of parathyroid gland (PTG) hyperplasia determined by cinacalcet and vitamin D have not been extensively investigated in humans. METHODS We performed histological analyses of 94 PTGs removed from 25 HP who underwent(More)
The major determinants of the poor prognosis of the patients with proximal-third gastric cancer (proximal gastric cancer or PGC) when compared with that of patients with more distally located gastric tumors (distal gastric cancer or DGC) rely both on the more advanced age and tumor stage at the moment of clinical presentation and on the higher postoperative(More)
Sarcopenia is one of the most striking effects of age, the causes and the pathogenic mechanisms being largely unknown. Unfortunately, there is limited information on the effect of aging on muscle protein breakdown in basal conditions. The present study aimed at investigating if skeletal muscle ubiquitn mRNA levels and proteasome activities vary with age in(More)
