ReviewTargeted Temperature Management in Spontaneous Intracerebral Hemorrhage: A Systematic Review.
Fever is common in neurocritical care patients and is associated with poor outcome. Targeted temperature management (TTM), i.e. therapeutic hypothermia or controlled normothermia, after acute brain injury has been studied as a neuroprotectant for several decades. In contrast to pharmacological agents with specific targets TTM affects multiple pathophysiological mechanisms and is primarily thought to attenuate secondary brain injury. Most promising results have been obtained from experimental studies on cerebral ischemia or traumatic brain injury showing beneficial effects of hypothermia on structural and functional outcome. ⋯ A positive influence of hypothermia has been observed in animal models of spontaneous ICH improving, among others, perihematomal edema, blood-brain barrier integrity, inflammation and thrombin-induced injury. However, results regarding functional outcome are conflicting. Little data is available on the effect of TTM after spontaneous ICH in humans. Single-center observational studies have shown reduced perihematomal edema under mild hypothermia and an association with favorable outcome. However, these beneficial effects on mortality and functional outcome have not been confirmed in randomized studies so far. Thus, results from ongoing, prospective randomized-controlled trials are highly anticipated.

ReviewProgress in Therapies for Myocardial Ischemia Reperfusion Injury.
Experimental studies of acute myocardial infarction have revealed that up to half of the final infarct size may be due to reperfusion injury rather than the initial ischemic incident. Research over the past three decades has deepened our understanding of the molecular mechanisms underlying ischemic reperfusion injury and several therapeutic strategies to decrease the incidence and severity of reperfusion injury have been explored. ⋯ Studies demonstrate that nonpharmacological and pharmacological conditioning can be used together as part of a multifaceted approach to improve clinical outcomes in patients with ischemic heart disease.

ReviewPharmacological Correction of Cystic Fibrosis: Molecular Mechanisms at the Plasma Membrane to Augment Mutant CFTR Function.
In the late 1980s, a loss-of-function mutation in the gene encoding for the cystic fibrosis transmembrane conductance regulator (CFTR) chloride channel was identified to be the primary cause of cystic fibrosis (CF); a fatal multiple-organ disorder that mostly affects Caucasians. To date, approximately 2000 genetic mutations have been identified in the CFTR gene (http://www.genet.sickkids.on.ca/cftr/app). The most common cause of morbidity and mortality in persons with CF is a progressive deterioration in lung function leading ultimately to respiratory collapse. ⋯ It is necessary to understand the biology of F508del-CFTR post-ER and at the plasma membrane where the protein might also confront the modifiers and how we can incorporate these components into CF therapeutics. Additionally, the notion that CF individuals would eventually benefit from more of a personalized medicine is becoming increasingly accepted. Here, we review how CF therapeutics may be simplified by understanding the complexities of rescued F508del-CFTR biology and eventually move toward more personalized medicine for patients suffering with CF.

ReviewEmerging Immunotargets and Immunotherapies in Prostate Cancer.
Innate and adaptive immunity are both involved in prostate cancer (PCa) carcinogenesis and progression. On this scenario, several immunotherapeutic approaches have been proposed and are presently under extensive investigation in PCa patients. Among emerging immune targets, immune checkpoint inhibitors such as anti-cytotoxic T-lymphocyteassociated protein 4 (CTLA-4), anti-Programmed death-1 (PD-1) and anti-Programmed death-ligand-1 (PD-L1) agents seem to represent the most promising candidate for these patients, together with oncolytic viruses and vaccines, used alone or in combined strategies. In this review, we focused on emerging immunotherapeutic approaches in patients with PCa, showing the rational for their association with current standard therapies including anti-androgen agents, chemo- or radiation therapy.

Cystic Fibrosis (CF) is a serious genetic condition caused by CF transmembrane conductance regulator (CFTR) mutation. CF patients have shortened lifespan due to airway obstruction, infection, and end-stage lung failure. ⋯ Gene therapy introduces correct CFTR gene into the affected airway epithelium leading to the functional expression of CFTR in CF patients. This review will sum up the current status in CF-cause targeting therapy.
