Sex Difference of Radiation Response in Occupational and Accidental Exposure
Conclusion and Outlook This review summarizes the data from major human studies on the health risks of radiation exposure and shows that sex can potentially influence the prolonged response to radiation exposure (Figure 1 and Tables 1, 2). These data suggest that long-term radiosensitivity in females is higher than that in males who receive a comparable dose of radiation. Our analysis of the literature agrees with the conclusions of the recent report on the Biological effects of ionizing radiation (BEIR VII) published in 2006 by the National Academy of Sciences (NAS), United States (National Research Council, 2006). The B...

Frequency of Hemorrhage on Follow Up Imaging in Stroke Patients Treated With rt-PA Depending on Clinical Course
Conclusions: Frequency of hemorrhagic transformation in Routine follow-up brain imaging and consecutive changes in therapeutic management were different depending on clinical course measured by NHISS score. Introduction Brain imaging 24–36 h after systemic thrombolysis for acute ischemic stroke is recommended in American Stroke Association and European Stroke Organization guidelines (1, 2). Brain imaging is performed to detect secondary bleeding or hemorrhagic transformation in order to adapt medical stroke prevention if necessary. Guideline recommendations are based on the results of the first study on rt-PA...

Adult and pediatric mechanical circulation: a guide for the hematologist.
Authors: Kreuziger LB, Massicotte MP Abstract Mechanical circulatory support (MCS) is the overarching term that encompasses the temporary and durable devices used in patients with severe heart failure. MCS disturbs the hematologic and coagulation system, leading to platelet activation, activation of the contact pathway of coagulation, and acquired von Willebrand syndrome. Ischemic stroke and major hemorrhage occur in up to 30% of patients. Hematologists are an essential part of the MCS team because they understand the delicate balance between bleeding and clotting and alteration of hemostasis with antithrombotic th...

Association Between Patient and Physician Sex and Physician-Estimated Stroke and Bleeding Risks in Atrial Fibrillation
ConclusionsOur study is the first to examine the association between patient and physician sex influences and stroke and bleeding risk estimation in AF. While there were differences in agreement between physician estimated stroke risk and calculated CHADS2 scores, these differences were small and unlikely to impact clinical practice; further, despite any perceived differences in the accuracy of risk assessment by sex, most patients received anticoagulation.

Oxidative Modified Fibrinogen in Cardiovascular Diseases
ConclusionsThe results show that the degree of impairment of fibrinogen functions in the cardiovascular diseases is related to the level of oxidative stress. Characterization of oxidative fibrinogen modification and its precise meaning to the function of fibrinogen in hemostasis appears to be extremely helpful to better understanding of thrombotic/bleeding complications linked with various cardiovascular diseases.AcknowledgementsThis work was supported by the Ministry of Health, Czech Republic, no. 00023736, by the Academy of Sciences, Czech Republic no.

The Canadian Community Utilization of Stroke Prevention Study in Atrial Fibrillation in the Emergency Department (C-CUSP ED)
ConclusionAn oral anticoagulation prescription tool was associated with an increase in new oral anticoagulation prescription in the ED, irrespective of whether an atrial fibrillation clinic follow-up was scheduled. The use of an atrial fibrillation clinic was associated with a trend to a higher rate of oral anticoagulation at 6-month follow-up.

Unusual Techniques for Preserving Surgical and Oncologic Safety in Hepatectomy of Advanced Adrenal Malignancy with Vena Cava and Liver Invasion
We report herein three cases of major hepatectomy with IVC invasion and discuss several surgical tips.Patients and MethodsFrom March 2011 to February 2014, we retrospectively reviewed three cases of adrenal malignancy with liver and IVC invasion. Based on the severity of the malignant tumor, each case illustrates a different method to address surgical complications and maintain oncologic safety. Case 1: A 34-year-old woman was diagnosed with adrenocortical tumor during medical examination. Tumor invaded the right lobe of the liver and very close to the IVC. Fortunately, there was little thrombosis inside the IVC; we perfor...

Studies: Low-Dose Aspirin May Not Prevent Initial Heart Attack, Stroke
Taking a low-dose aspirin every day has long been known to cut the chances of another heart attack, stroke or other heart problem in people who already have had one, but the risks don’t outweigh the benefits for most other folks, major new research finds. Although it’s been used for more than a century, aspirin’s value in many situations is still unclear. The latest studies are some of the largest and longest to test this pennies-a-day blood thinner in people who don’t yet have heart disease or a blood vessel-related problem. One found that aspirin did not help prevent first strokes or heart attacks...

Patients ’ Priorities for Oral Anticoagulation Therapy in Non-valvular Atrial Fibrillation: a Multi-criteria Decision Analysis
DiscussionAlthough the relative impact of convenience on therapy value is small, patients have different preferences for options within convenience criteria. Besides considerations on safety and effectiveness, physicians should also discuss attributes of convenience with patients, as it can be assumed that alignment to patient preferences in drug prescription and better patient education could result in higher adherence.

Clinical Management of Bleeding Risk With Antidepressants.
CONCLUSIONS: Clinicians must be aware of the risk of bleeding with SRI use, especially for patients taking NSAIDs. Patient education is prudent for those prescribed NSAIDs and SRIs concurrently. PMID: 30081645 [PubMed - as supplied by publisher]

Electronic physician notifications to improve guideline-based anticoagulation in atrial fibrillation: a randomized controlled trial
ConclusionsElectronic physician notification did not increase anticoagulation in patients with atrial fibrillation at elevated stroke risk. Primary care physicians did not prescribe anticoagulants because they perceived the bleeding risk was too high or stroke risk was too low.Trial RegistrationClinicalTrials.gov identifier NCT02950285

Perceived Advantages and Disadvantages of Oral Anticoagulants, and the Trade-offs Patients Make in Choosing Anticoagulant Therapy and Adhering to Their Drug Regimen
Oral anticoagulant therapy (OAT) is proven to be highly effective for stroke prevention in patients suffering from atrial fibrillation (AF) [1,2]. Vitamin K antagonists (VKAs), particularly warfarin, which is the most commonly used VKA, have long been the standard of care to prevent AF-related stroke [3]. However, in recent years the European Medicines Agency has approved a number of direct oral anticoagulants (DOACs) as (possible) alternatives to VKAs. The perceived benefits of DOACs include their high efficacy and low risk of bleeding, the rapid onset/offset of action, fewer food and drug interactions, and predictable ph...
