<p>Several studies have highlighted the detrimental effects of alcohol dependence upon bone health, but the majority of data relate to male alcoholics. In general, these effects are considered to be either a direct toxic effect on bone or related to confounding lifestyle factors linked to alcohol dependence. Given the rising prevalence of alcohol dependence in young women, data relating to this group are timely. We performed a study to assess bone health in this population and specifically to study change in bone turnover following admission to an alcohol detoxification unit in New Zealand.</p>

Thrombotic microangiopathy (TMA) is a rare phenomenon, which is severe pathology based on systemic microvascular thrombosis. TMA is characterized by thrombocytopenia and signs of microangiopathic hemolytic anemia. The review presents a modern data on the pathogenesis of tumor-associated thrombotic microangiopathy, considers the interaction of various effectors related to both tumor growth and metastasis process ― immune system activation, endotheliopathy formation, use of chemotherapeutic agents and targeted therapy in the pathogenesis of various forms of TMA. The interaction between the tumor tissue, hemostasis and immune systems are of the type of cascade of mutual activation, thus leading to the formation of a vicious circle, resulting in damage to endothelium and thrombosis in the microcirculatory channel, that is, the development of TMA. The formation of thromboembolism, which includes tumor tissue in the microvessels of the lungs, contributes to the development of pulmonary tumor thrombotic microangiopathy (PTTM). Сancer patients have higher vWF levels and lower ADAMTS13 levels or/and activity than the general population, often also depending on the stage of cancer: vWF and ADAMTS13 have been shown to be associated with thrombotic complications in cancer patients, and ADAMTS13 shows prognostic potential. Increased expression of complement proteins and/or activation of complement during chemotherapy, infectious and inflammatory complications may also cause TMA development. Pathogenesis of thrombotic microangiopathy also is associated with numerous chemotherapeutic agents, such as mitomycin C, gemcitabine, cisplatin, carboplatin and Bevacizumab, an inhibitor of VEGF. This may be the result of both the direct toxic effect of the drug on endothelium and damage of it by immune complexes caused by expression of the VEGF-antibodies. Usage of number of chemotherapeutic agents, especially anti-VEGF and tyrosine kinase inhibitors, which have a direct toxic effect on endothelium, are associated with the development of TMA. Mechanisms causing the development of TMA are considered as components of the hemostasis system, leading to the development of chronic, long-lasting disorders of the hemostasis system (chronic DIC syndrome) and are associated with high incidence of thrombotic complications.

There is an increasing awareness of the arrhythmogenic potential of cancer therapies, and the challenges they create in treating patients. As in the general population, the arrhythmia most frequently observed in patients undergoing cancer treatment is atrial fibrillation. Atrial fibrillation may occur as a result of the proinflammatory state of cancer, postoperatively (particularly in thoracic malignancies), or as a direct toxic effect of the chemotherapeutic agent. Cancer patients with atrial fibrillation may often have an increase in both thromboembolic and haemorrhagic risk. Therefore, the risks and benefits of anticoagulation should be carefully considered on a case-by-case basis.
