BACKGROUND: Carbon monoxide (CO) inhalation protects organ by reducing inflammation and cell death during transplantation processes in animal model. However, using CO in clinical transplantation is difficult due to its delivery in a controlled manner. A manganese-containing CORM-401 has recently been synthesized which can efficiently deliver 3 molar equivalents of CO. We report the ability of this anti-inflammatory CORM-401 to reduce ischemia reperfusion injury associated with prolonged cold storage of renal allografts obtained from donation after cardiac death in a porcine model of transplantation...

Artemisiae Argyi Folium, the dried leaves of Artemisia argyi, has been widely used in traditional Chinese and folk medicines for treatment of hemorrhage, pain, and skin itch. Phytochemical studies indicated that volatile oil, organic acid and flavonoids were the main bioactive components in Artemisiae Argyi Folium. Compared to the volatile compounds, the research of nonvolatile compounds in Artemisiae Argyi Folium are limited. In the present study, an accurate and reliable fingerprint approach was developed using HPLC for quality control of Artemisiae Argyi Folium...

BACKGROUND: Predicting the fate of patients who are given a misdiagnosis of aneurysmal subarachnoid hemorrhage (aSAH) remains unclear. The purpose was to examine factors associated with initial misdiagnosis of aSAH and to investigate the impact of initial misdiagnosis of aSAH on clinical outcomes. METHODS: Between January 2007 and December 2015, medical records and radiographic data for 3118 consecutive patients with aSAH were reviewed. There were 33 patients who had been documented with an initial misdiagnosis of aSAH, and all met the following criteria: (1) failure to correctly identify aSAH upon initial presentation to health care professionals; and 2) subsequently documented aSAH after the initial misdiagnosis...

BACKGROUND: The World Health Organization estimates the prevalence of preterm birth to be 5-18% across 184 countries of the world. Statistics from countries with reliable data show that preterm birth is on the rise. About a third of neonatal deaths are directly attributed to prematurity and this has hindered the achievement of Millennium Development Goal-4 target. Locally, few studies have looked at the prevalence of preterm delivery and factors associated with it. This study determined the prevalence of preterm birth and the factors associated with preterm delivery at Kenyatta National Hospital in Nairobi, Kenya...

The rupture of saccular intracranial aneurysms (IA) is the commonest cause of non-traumatic subarachnoid hemorrhage (SAH)—the most serious form of stroke with a high mortality rate. Aneurysm walls are usually characterized by an active inflammatory response, and NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells) has been identified as the main transcription factor regulating the induction of inflammation-related genes in IA lesions. This transcription factor has also been related to IA rupture and resulting SAH...

Case: We present the case of a 21-year-old man who fell from a roof, sustaining a displaced sacral fracture with pelvic instability. He developed acute respiratory distress syndrome (ARDS) within 24 hours of injury. Placement of the pelvic C-clamp resulted in rapid resolution of pulmonary dysfunction, allowing for definitive internal fixation. Conclusion: The C-clamp is most commonly used to control hemorrhage in unstable posterior pelvic ring injuries. Our case demonstrates a rare use of the C-clamp to stabilize the posterior pelvis in a patient with an unstable sacral fracture and ARDS, to rapidly improve pulmonary function prior to definitive surgery...

Clinical and technological advances promoting early hemorrhage control and physiologic resuscitation as well as early diagnosis and optimal treatment of sepsis have significantly decreased in-hospital mortality for many critically ill patient populations. However, a substantial proportion of severe trauma and sepsis survivors will develop protracted organ dysfunction termed chronic critical illness (CCI), defined as ≥14 days requiring intensive care unit (ICU) resources with ongoing organ dysfunction...

INTRODUCTION: Hemorrhagic shock is a major cause of death after trauma. An additional blunt chest trauma independently contributes to mortality upon the development of an acute lung injury (ALI) by aggravating pathophysiological consequences of hemorrhagic shock. The maintenance of hydrogen sulfide availability is known to play an important role during hemorrhage and ALI. We therefore tested the impact of a genetic 3-mercaptopyruvate sulfurtransferase mutation (Δ3-MST) in a resuscitated murine model of traumatic-hemorrhagic shock...

Background Although transarterial embolization (TAE) can powerfully control postpartum hemorrhage (PPH), clinical failure of TAE is not uncommon. Purpose To discover whether any parameters could predict timely clinical failure of TAE, then whether a supplementary intervention could be promptly initiated. Material and Methods We retrospectively analyzed 118 TAE procedures in 113 patients with PPH performed at our institution between January 2012 and May 2015. The patients were divided into the following groups: clinically successful TAE and failed TAE...

Urbanization and rural-urban migration are two factors driving global patterns of disease and mortality. There is significant concern about their potential impact on disease burden and the effectiveness of current control approaches. Few attempts have been made to increase our understanding of the relationship between urbanization and disease dynamics, although it is generally believed that urban living has contributed to reductions in communicable disease burden in industrialized countries. To investigate this relationship, we carried out spatiotemporal analyses using a 48-year-long dataset of hemorrhagic fever with renal syndrome incidence (HFRS; mainly caused by two serotypes of hantavirus in China: Hantaan virus and Seoul virus) and population movements in an important endemic area of south China during the period 1963-2010...

Resting-state functional magnetic resonance imaging (RS-FMRI) has been widely used to map brain functional connectivity, but it is unclear how to probe connectivity within and around lesions. Here we characterize RS-FMRI signal time-course properties and evaluate different seed placements within and around hemorrhagic traumatic axonal injury lesions. RS-FMRI was performed on a 7 Tesla scanner in a patient who recovered consciousness after traumatic coma and in three healthy controls. Eleven lesions in the patient were characterized in terms of: 1) temporal signal-to-noise ratio (tSNR); 2) physiological noise, through comparison of noise regressors derived from the white matter (WM), cerebrospinal fluid (CSF) and gray matter (GM); and 3) seed-based functional connectivity...

Fibrinolysis is a complex process that controls both hemostasis and thrombosis. The regulation of the fibrinolytic system is mediated through a wide array of cofactors and inhibitors that maintain the hemostatic balance in a delicate equilibrium. As a consequence, disturbances in the fibrinolysis pathway are associated with various disease states, ranging from thrombotic to hemorrhagic clinical phenotypes. In particular, a number of inherited and acquired disorders are associated with an enhanced fibrinolysis leading to a bleeding tendency that in some cases may be life-threatening...

BACKGROUND: Previous studies suggested that acute respiratory infection (ARI) could trigger stroke and that use of nonsteroidal anti-inflammatory drugs (NSAIDs) was associated with increased risk of stroke. In many countries, NSAIDs have been widely used among patients with ARI or common cold for pain and fever relief. However, studies evaluating whether NSAIDs use during ARI episodes may further increase the risk of stroke were very limited. METHODS AND RESULTS: During 2007 to 2011, 29 518 patients with an incident hospitalization of stroke were identified...
