Lung cancer is the leading cause of mortality world-wide. Non Small Cell Lung Cancer (NSCLC) is a particularly aggressive cancer, the optimum management of which is still being determined. In the next years modest survival improvement can be expected by chemotherapy. ⋯ A number of studies suggest that the PI3K/Akt signaling pathway is central to NSCLC growth and survival. Given the importance of activated PI3K signaling in cancer, several PI3K inhibitors are currently one of the most recent drug targets in oncology, with several small molecules in early stages of clinical development. This review will focus on the role of EGFR, ALK, MET, and PI3K inhibitors in the treatment of NSCLC.

Characteristic clinical manifestations of AFD such as acroparesthesias, angiokeratoma, corneal opacity, hypo/ and anhidrosis, gastrointestinal symptoms, renal and cardiac dysfunctions can occur in male and female patients, although heterozygous females with AFD usually seem to be less severely affected. The most prominent CNS manifestations consist of cerebrovascular events such as transient ischaemic attacks (TIAs) and (recurrent) strokes. For the most part, CNS complications in AFD have been attributed to cerebral vasculopathy, including anatomical abnormalities. ⋯ Due to both somatic and psychological impairment, health-related quality of life (QoL) is considerably reduced in patients with Fabry disease. Targeted screening for Fabry disease among young individuals with stroke seems to disclose unrecognized cases and may therefore very well be recommended as routine in the future. Furthermore, ischemic stroke is related to inflammation and arterial stiffness and no study had addressed this relationship in patients with AF disease and cerebrovascular disease, so this topic could represent a possible future research line.

Resveratrol (3,5,4'-trihydroxy-trans-stilbene) is a non-flavonoid polyphenol that may be present in a limited number of foodstuffs such as grapes and red wine. Resveratrol has been reported to exert a plethora of health benefits through many different mechanisms of action. This versatility and presence in the human diet have drawn the worldwide attention of many research groups over the past twenty years, which has resulted in a huge output of in vitro and animal (preclinical) studies. ⋯ However, safety concerns remain unsolved regarding chronic consumption of high RES doses, specially in medicated people. This review will focus on the currently available evidence regarding resveratrol's effects on humans obtained from randomized clinical trials. In addition, we will provide a critical outlook for further research on this molecule that is evolving from a minor dietary compound to a possible multi-target therapeutic drug.

Dyslipidemia is one of the main risk factors leading to cardiovascular disease (CVD). The standard of therapy, administration of statins, in conjunction with lifestyle and habit changes, can improve high cholesterol levels in the majority of patients. However, some patients with familial hypercholesterolemia (FH) need low-density-lipoprotein cholesterol (LDL-C) apheresis, as the available medications fail to reduce LDL-C levels sufficiently even at maximum doses. ⋯ Mipomersen has been investigated in different indications including homozygous and heterozygous FH, as well as in high-risk hypercholesterolemic patients. Recent phase II and III clinical studies have shown a 25-47% reduction in LDL-C levels in mipomersen-treated patients. If future studies continue to show such promising results, mipomersen would likely be a viable additional lipid-lowering therapy for high-risk populations.

Fabry disease (FD) is a rare X-linked lysosomal storage disorder caused by a deficiency of the enzyme α-galactosidase A. FD causes glycolipids, such as globotriaosylceramide (Gb3), to accumulate in the vascular endothelium of several organs (Fig. 2), including the skin, kidneys, nervous system, and heart, thereby triggering inflammation and fibrosis. These processes generally result in organ dysfunction, which is usually the first clinical evidence of FD. ⋯ The resultant storage of undegraded glycolipids leads to the progressive development of potentially life-threatening manifestations affecting multiple organ systems in the body. The Mainz Severity Score Index (MSSI) (Table 12), a scoring system for patients with Fabry disease has been proven to be representative in patients with 'classic' Fabry disease and may be useful for monitoring clinical improvement in patients receiving enzyme replacement therapy. The MSSI of patients with AFD was significantly higher than that of patients with other severe debilitating diseases.
