INTRODUCTION: Venous thromboembolism (VTE) during hospitalization is a serious and potentially fatal condition. Despite its effectiveness, evidence-based thromboprophylaxis is still underutilized in many countries including Saudi Arabia. OBJECTIVE OF THE STUDY: Our objectives were to determine how often hospital-acquired VTE patients received appropriate thromboprophylaxis, VTE-associated mortality, and the percentage of patients given anticoagulant therapy and adherence to it after discharged...

Heavy exertion as a trigger of cardiac events has been known since antiquity as it was already described in 492 BC in the famous Athens Marathon. Myocardial infarction occurring after physical exertion accounts for about 4% of myocardial infarctions. It is more common in men and younger patients. It usually occurs during intense efforts and especially in inactive people with multiple risk factors. It would be more severe with more frequent Q waves of necrosis on the victims' electrocardiograms, with greater troponin release and a more raised GRACE score...

Factor XIa (FXIa) is a blood coagulation enzyme that is involved in the amplification of thrombin generation. Mounting evidence suggests that direct inhibition of FXIa can block pathologic thrombus formation while preserving normal hemostasis. Preclinical studies using a variety of approaches to reduce FXIa activity, including direct inhibitors of FXIa, have demonstrated good antithrombotic efficacy without increasing bleeding. On the basis of this potential, we targeted our efforts at identifying potent inhibitors of FXIa with a focus on discovering an acute antithrombotic agent for use in a hospital setting...

Vitamin K antagonists (VKA) have long been the default drugs for anticoagulant management in venous thrombosis. While efficacious, they are difficult to use due to interpatient dose-response variability and the risks of bleeding. The approval of fondaparinux, a heparin-derived factor Xa (fXa) inhibitor, provided validation for the development of direct oral anticoagulants (DOAC), and currently such inhibitors of thrombin and fXa are in clinical use. These agents can be used without regular coagulation monitoring but the inherent risk of bleeding complications associated with blocking the common coagulation pathway remains...

Primary effort thrombosis is a noniatrogenic deep vein thrombosis of the upper extremity. The incidence of this condition is 1 to 2 in 100,000 per year. The risk factors and typical patient population differ from other thrombotic events. Patients with primary effort thrombosis are typically young, athletic, and lack comorbidities. Due to its low incidence and unique risk factors, primary effort thrombosis often is misdiagnosed as a musculoskeletal injury. However, early recognition, initial testing with Doppler ultrasound, and immediate referral to a vascular center is essential to achieve optimal outcomes...

We report a case of upper extremity deep venous effort thrombosis complicating a thoracic outlet syndrome in a 44-year-old patient. The appearance of this complication was sudden. A clinical examination followed by imaging with phlebography leads to a quick diagnosis. Effort thrombosis is a classic example of an entity which, if treated correctly, has minimal long-term sequelae but, if ignored, is associated with significant long-term morbidity. An appropriate medical and interventional care has been implemented as soon as possible...

A meta-analysis showed that methodological differences in prevalence studies such as a sample survey design or census design may be responsible for some of the variance in BS prevalence reported across countries, in addition to a true geographic variation. Efforts towards developing a data driven core set of outcome measures for clinical trials is continuing. Multimodal imaging using color fundus photography, fluorescein angiography, and optical coherence tomography is essential in visualising diagnostic features, detecting structural changes, and monitoring disease activity and response to treatment in Behçet's uveitis...

Pediatric hospital acquired venous thromboembolism (HA-VTE) is an increasing problem with an estimated increase from 5.3 events per 10,000 pediatric hospital admissions in the early 1990s to a current estimate of 30-58 events per 10,000 pediatric hospital admissions. Pediatric HA-VTE is associated with significant morbidity and mortality. The etiology is multifactorial but central venous catheters remain the predominant risk factor. Additional HA-VTE risk factors include both acquired (recent surgery, immobility, inflammation, and critical illness) and inherited risk factors...

BACKGROUND: Antiphospholipid syndrome (APS) is a systemic autoimmune disease characterized by arterial or venous thrombosis (or both) and/or pregnancy morbidity in association with the presence of antiphospholipid antibodies. The prevalence is estimated at 40 to 50 cases per 100,000 people. The most common sites of thrombosis are cerebral arteries and deep veins of the lower limbs. People with a definite APS diagnosis have an increased lifetime risk of recurrent thrombotic events. OBJECTIVES: To assess the effects of antiplatelet or anticoagulant agents, or both, for the secondary prevention of recurrent thrombosis, particularly ischemic stroke, in people with antiphospholipid syndrome...

On the effort to screen antibiotics against Methicillin resistant Staphylococcus aureus (MRSA), an actinomycete strain which can produce bactericidal compound was isolated from a marine sponge of Kanyakumari Coast, India. Two anti-MRSA compounds (PVI401 and PVI402) were isolated from the fermentation plates of Streptomyces pharmamarensis ICN40. TLC bioautography analysis yielded two active spots with Rf value of 0.75 (PVI401) and 0.8 (PVI402) from the crude extract. Both the compounds were characterized by HR-LC-MS analysis...

There currently is renewed interest in blood clotting Factor XII as a potential target for thrombosis inhibition. Historically untargeted, there is little drug information with which to start drug candidate searches. Typical high-throughput screening can identify potential drug candidates, but is inefficient. Virtual high-throughput screening can be used to raise efficiency by focusing experimental efforts on compounds predicted to be active and is applied here to identify new Factor XIIa inhibitors. We combine principal component analysis, genetic algorithm and support vector machine to create the models used in the virtual high-throughput screening...

In proctology patients can often be helped with very little effort. With knowledge of the most common disease symptoms the treating physician can in many cases correctly recognize the cause of the complaints and initiate the appropriate therapy or arrange referral to a proctological institution. This article aims to briefly and succinctly present the most common diseases in proctology (e.g. mariscae, hemorrhoids, anal fissures, perianal venous thrombosis, abscesses and fistulas, condyloma acuminatum and anal carcinoma) and to provide the treating internist, even outside of gastroenterology, assistance with the management of proctological symptoms...

The use of novel oral anticoagulants (NOACs) has increased in recent times in an effort to overcome the shortcomings of warfarin. They are being used primarily for the prevention of thrombosis caused by atrial fibrillation and offer the advantages of having fewer drug interactions than warfarin, no dietary restrictions, and no requirement for regular blood tests. Although there is reportedly less postoperative bleeding even if the drug is not discontinued during procedures that can cause local bleeding, such as dental procedures, no well-designed clinical studies have assessed postoperative bleeding associated with the use of these drugs...

To overcome the limitations of metallic stents, the development of the bioresorbable vascular scaffold started about 30 years ago. Researchers anticipated a transformative revolution from "vascular reparative therapy" by BRS at the beginning of its development. To date, there are five commercially available bioresorbable scaffolds which have already gained CE mark. However, recent studies, including randomised trials and meta-analyses evaluating clinical results of BRS, have raised concerns about the safety and efficacy of the device in the first few years prior to its complete bioresorption, compared to contemporary metallic DES...

Acute intestinal ischemic injury (i3) is a life-threatening condition with disastrous prognosis, which is currently difficult to diagnose at the early stages of the disease; a rapid diagnosis is mandatory to avoid irreversible ischemia, extensive bowel resection, sepsis and death. The overlapping protein expression of liver and gut related to the complex physiopathology of the disease, the heterogeneity of the disease and its relative rarity could explain the lack of a useful early biochemical marker of i3...

Passive leg raising is widely used in clinic, but it lacks of specialized mechanical raise equipment. It requires medical staff to raise leg by hand or requires a multi-functional bed to raise leg, which takes time and effort. Therefore we have developed a new medical electric leg-raising machine. The equipment has the following characteristics: simple structure, stable performance, easy operation, fast and effective, safe and comfortable. The height range of the lifter is 50-120 cm, the range of the angle of raising leg is 10degree angle-80degree angle, the maximum supporting weight is 40 kg...
