The Impact of Climate Change on Agricultural Insect Pests.

Climate change and global warming are of great concern to agriculture worldwide and are among the most discussed issues in today's society. Climate parameters such as increased temperatures, rising atmospheric CO levels, and changing precipitation patterns have significant impacts on agricultural production and on agricultural insect pests. Changes in climate can affect insect pests in several ways.

Antiviral Effects of Pomegranate Peel Extracts on Human Norovirus in Food Models and Simulated Gastrointestinal Fluids.

Human noroviruses (HuNoV) are the dominant cause of viral gastroenteritis in all age groups worldwide. In this study, we investigated the effects of pomegranate peel extract (PPE) on the reduction of HuNoV in different food models, on surfaces of fresh produce (green onion and cherry tomato), in low-fat milk, and simulated gastrointestinal fluids. The antiviral efficacy of PPE against HuNoV was evaluated by quantifying the number of residual virus genomes using a quantitative reverse transcription PCR (qRT-PCR) assay.

Maintenance phase treatment of psychotic disorders in outpatients from Serbia - focus on long-term benzodiazepine use.

Prescribing trends in maintenance therapy of patients with primary psychotic disorders (PSD) may vary worldwide. Present study aimed to investigate prescription patterns in a sample of outpatients with PSD from Serbia. In a sample of 73 PSD outpatients we analysed the rate of antipsychotic polypharmacy and psychotropic polypharmacy, concomitant continual benzodiazepine use, and associations between therapy, psychotic symptoms and quality of life.

Dabigatran - Metabolism, Pharmacologic Properties and Drug Interactions.

The superiority of dabigatran has been well proven in the standard dosing regimen in prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation (NVAF) and extended venous thromboembolism (VTE) treatment. Dabigatran, an anticoagulant with a good safety profile, reduces intracranial bleeding in patients with atrial fibrillation and decreases major and clinically relevant non-major bleeding in acute VTE treatment. However, several important clinical issues are not fully covered by currently available directions with regard to dabigatran administration.

Practical Aspects of Monitoring of Antiplatelet Therapy.

Despite the application of new antiplatelet drugs (prasugrel and ticagrelor), dual antiplatelet therapy with clopidogrel and aspirin remains the standard for patients with acute coronary syndrome undergoing percutaneous coronary intervention, especially in countries of low socioeconomic status. Regardless of the proven benefits, numerous studies have shown that certain groups of patients who receive standard doses of clopidogrel and aspirin do not respond adequately, and many of them also exhibit adverse cardiovascular events. Studies have shown that the risk of stent thrombosis and ischemic complications is higher in patients with: acute coronary syndrome, diabetes mellitus, thrombocytosis, reduced systolic function of the left ventricle with ejection fraction less than 30%, presence of multiple stents, longer and thinner stents, and renal failure.

Mineralocorticoid receptor antagonists, a class beyond spironolactone--Focus on the special pharmacologic properties of eplerenone.

The renin-angiotensin-aldosterone system can be blocked at specific levels by using different classes of pharmacologic agents, including angiotensin-converting-enzyme inhibitors, angiotensin II receptor blockers and mineralocorticoid receptor antagonists. Broad use of the latter, such as spironolactone, has been limited by significant incidence of gynecomastia and other sex-related adverse effects. These problems can be overcome with use of eplerenone, a selective mineralocorticoid receptor antagonist.

[Contribution of novel anticoagulants fondaparinux and dabigatran to venous thromboembolism prevention].

The data that episodes and sequels of venous thromboembolism (VTE) are recorded in a significant percentage of patients receiving standard anticoagulants as VTE prophylaxis (unfractionated, low-molecular-weight heparin and vitamin K inhibitors) as well as the fact that these drugs have significant limitations and that they may cause serious side-effects in some patients indicate the need for the introduction of new anticoagulant drugs. Fondaparinux, a selective inhibitor of Factor Xa, administered following major orthopedic surgeries having a high risk for the development of VTE, is more efficient than enoxaparin sodium used in European and North-American approved doses. The increased incidence of major bleeding (excluding fatal) due to fondaparinux could be perhaps lowered by dosage reduction in patients with a mildly decreased creatinine clearance.

The role of glycemia in acute heart failure patients.

Acute heart failure (AHF) is one of the most important cardiovascular syndromes associated with high cardiovascular morbidity, and is the major cause of admission in emergency departments worldwide. The clinical complexity of AHF has significantly increased, mostly due to the comorbidities: diabetes, arterial hypertension, dyslipidemia, obesity, peripheral vascular disease, renal insufficiency and anemia. Numerous clinical trials have demonstrated a frequent association of AHF and diabetes.

[Contemporary approach to primary prophylaxis of venous thromboembolism regarding the impact of risk factors on anticoagulation therapy duration].

Adequate thromboprophylaxis primarily requires timely detection of reversible and irreversible risk factors of venous thromboembolism (VTE) and their categorization. It is important to note that the highest percentage ofVTE episodes occur in non-surgical (medical) patients and that VTE develops in a large number of surgical patients upon hospital discharge; this emphasizes the need for adequate VTE prevention in inflammatory diseases, acute medical illness and other medical diseases as well as for prolonging and optimizing the anticoagulant regimen after surgical intervention in the primary VTE prophylaxis. As almost completely unrecognized and neglected major risk factors of VTE in clinical practice, we particularly point out the chronic obstructive pulmonary disease (COPD) and heart failure, especially in NYHA functional class III and IV patients with significantly reduced left heart ventricle.
