Four years after the latest edition, the 2015 non-ST-segment elevation acute coronary syndromes guidelines of the European Society of Cardiology have been published. Novel aspects include a new diagnostic algorithm for non-ST-segment elevation myocardial infarction using high-sensitivity cardiac troponins as well as guidance on cardiac rhythm monitoring duration. A large section is dedicated to antiplatelet therapy including initiation and duration of dual-antiplatelet therapy as well as the management of patients requiring, at the same time, long-term oral anticoagulation. New sections include the management of antiplatelet agent in patients requiring coronary artery bypass surgery and of acute bleeding events related to antiplatelet agents, vitamin K antagonist (VKA), and non-VKA oral anticoagulant drugs. Current evidence supports the radial access over the femoral one for coronary angiography and percutaneous revascularization. 相似文献

Breast-conserving therapy, which includes wide local excision of the tumor followed by irradiation, has become a standard
treatment option for women with early-stage invasive breast cancer. The potential advantages of conservative breast surgery
include the minor outpatient nature of the procedures, lower incidence of post-operative pain and complications, preservation
of the breast and nipple areolar complex, and shorter delay to adjuvant therapy. However, not all patients are optimal candidates
for breast-conserving procedures. Oncoplastic techniques combine the removal of breast cancer tumors in combination with either
local volume replacement techniques to correct small defects, or by immediate reconstruction of larger defects using techniques
of plastic surgery with or without contralateral breast procedures for symmetry. Therefore, oncoplastic techniques offer the
potential to perform a wider excision of the tumor with an improved cosmetic result, thus potentially increasing the eligible
pool for breast conservation. 相似文献

Abdominal pain is one of the common symptoms reported by children in urgent care clinics. While most children tend to have self-limiting conditions, the treating pediatrician should watch out for underlying serious causes like intestinal obstruction and perforation peritonitis, which require immediate referral to an emergency department (ED). Abdominal pain may be secondary to surgical or non-surgical causes, and will differ as per the age of the child. The common etiologies for abdominal pain presenting to an urgent care clinic are acute gastro-enteritis, constipation and functional abdominal pain; however, a variety of extra-abdominal conditions may also present as abdominal pain. Meticulous history taking and physical examination are the best tools for diagnosis, while investigations have a limited role in treating benign etiologies. 相似文献

A peripherally inserted central catheter (PICC) is a thin catheter that is inserted via arm veins and threaded near the heart, providing intravenous access. The final catheter tip position is always confirmed on a chest radiograph (CXR) immediately after insertion since malpositioned PICCs can cause potentially life-threatening complications. Although radiologists interpret PICC tip location with high accuracy, delays in interpretation can be significant. In this study, we proposed a fully-automated, deep-learning system with a cascading segmentation AI system containing two fully convolutional neural networks for detecting a PICC line and its tip location. A preprocessing module performed image quality and dimension normalization, and a post-processing module found the PICC tip accurately by pruning false positives. Our best model, trained on 400 training cases and selectively tuned on 50 validation cases, obtained absolute distances from ground truth with a mean of 3.10 mm, a standard deviation of 2.03 mm, and a root mean squares error (RMSE) of 3.71 mm on 150 held-out test cases. This system could help speed confirmation of PICC position and further be generalized to include other types of vascular access and therapeutic support devices. 相似文献

Cardiac hemangiomas are rare benign tumors. Here, we report the case of a man in his 30s who had a cardiac hemangioma with no symptoms. He was being treated with β-blockers for chronic heart failure with hypertensive heart disease at Osaka Minato Central Hospital. Routine echocardiography revealed a mobile spherical mass in the left ventricle that had not been detected on echocardiography performed 4 months previously. Subsequently, the tumor was excised to prevent potential embolic events and was pathologically diagnosed as a cardiac hemangioma. This case demonstrates the relatively rapid progress of a cardiac hemangioma regardless of β-blocker administration, which is occasionally used for the treatment of hemangiomas. The efficacy of β-blockers in treating cardiac hemangiomas may vary according to the type of β-blocker. Echocardiography is useful in screening and follow-up of cardiac hemangiomas; however, additional imaging modalities are needed for differential diagnosis. 相似文献

The current study shows an advanced synesthetic technique of a nitrate-fertilizer with a controlled release behavior into different soils (normal and acidic agriculture soils solutions) at different climate temperatures. The environmentally friendly and the biocompatible layered double hydroxide (LDH) clay material was used as a host to accommodate the nitrate anion into its interlayer gallery by applying a reconstruction-incorporation technique (the memory effect property of LDH that allows calcined LDH to memorize its original structure). The prepared materials were characterized by different spectroscopic techniques including; X-ray powder spectroscopy, IR, SEM, TEM, and TGA analyses. A remarkable loading ratio of the nitrate anion fertilizer was recorded into the LDH structure. Around 90 wt% of the intercalated nitrate anion was released in a sustained controlled behavior over around 24 days, while the same amount of nitrate was released over 10 days in the acidic soil. Accordingly, the present study offers a new passway for the formulation of controlled release fertilizers by using the hosting anionic clay LDH materials. 相似文献
