Aerobic exercise training without significant weight loss improves metabolic profile and exerts anti-inflammatory effects in patients with type 2 DM.

Abstract. With a lifetime risk estimated to be one in eight in industrialized countriesBreast cancer is the most frequently diagnosed cancer and the second leading cause of cancer-related death among women worldwide. According to the American Cancer Society about 12% U.S. women will develop breast cancer during their lifetime. Moreover, in 2015, about 2,300 men were diagnosed with breast cancer and 440 died from the disease (1, 2).In approximately 90% of breast cancer cases, estrogen receptor α (ERα), progesterone receptor (PR), or the human epidermal growth factor receptor2 (HER2/ERBB2) protooncogenic receptor are expressed. In many of these patients, treatment with anti-estrogens (e.g. aromatase inhibitors, tamoxifen, fulvestrant) and HER2-targeted agents has improved their survival significantly (3, 4). However, despite 35

Diabetes mellitus (DM) is associated with an increased incidence of cardiovascular events and microvascular complications. These complications contribute to the morbidity and mortality associated with DM. There is increasing evidence supporting a role for matrix metalloproteinases (MMPs) and their inhibitors (tissue inhibitors of matrix metalloproteinases - TIMPs) in the atherosclerotic process. However, the relationship between MMPs/TIMPs and diabetic angiopathy is less well defined. Hyperglycemia directly or indirectly (eg, via oxidative stress or advanced glycation products) increases MMP expression and activity. These changes are associated with histologic alterations in large vessels. On the other hand, low proteolytic activity of MMPs contributes to diabetic nephropathy. Within atherosclerotic plaques an imbalance between MMPs and TIMPs may induce matrix degradation, resulting in an increased risk of plaque rupture. Furthermore, because MMPs enhance blood coagulability, MMPs and TIMPs may play a role in acute thrombotic occlusion of vessels and consequent cardiovascular events. Some drugs can inhibit MMP activity. However, the precise mechanisms involved are still not defined. Further research is required to demonstrate the causative relationship between MMPs/TIMPs and diabetic atherosclerosis. It also remains to be established if the long-term administration of MMP inhibitors can prevent acute cardiovascular events.
