CoNS are common in skin flora and are often mistaken as contamination. Conversely, CoNS can also be implicated in severe and life-threatening bacteremia requiring prompt treatment. A gray area in terms of treatment approach exists for health care providers. The primary aim of this study was to examine predictive factors in patients who have positive CoNS blood cultures that met the CDC case definition of a laboratory confirmed bloodstream infection (LCBI-II) that were subsequently found to have clinically significant true bacteremia. Methods: A retrospective cohort of 288 patients that had at least two separate blood cultures positive for a coagulase negative Staphylococci between November 1st, 2017, and November 1st, 2018, were examined to determine if there were any patient specific factors that would indicate a true bacteremia with CoNS. Results: Retrospective regression analysis demonstrated that those subjected to antibiotics for two days or more (OR = 3.01), those subjected to antibiotics for seven days or more (OR = 2.86), and patients with central access (OR = 4.06) were more likely to have a true infection. Although not statistically significant, an association was also found in immunosuppressed patients (OR = 1.65), and in patients with implanted hardware (OR = 1.16). Conclusion: Patients receiving antibiotics for greater than two days and patients with a central line were more likely to have a true bloodstream infection with coagulase negative Staphylococci.展开更多

In this paper,we study the class of security risks that are inherent to the dependence structure in software with vulnerabilities and exhibit a "cascading" effect. We present a measurement framework for evaluating these metrics,and report a preliminary case study on evaluating the dependence-induced security risks in the Apache HTTP Server. The experiment results show that our framework can not only clearly analyze the root cause of the security risks but also quantitatively evaluate the attack consequence of the risks.展开更多

It can be induced by a variety of events such as hypoxia, nutrient-starvation, and mechanical damage. Many neurological disorders such Parkinson’s disease, Alzheimer’s disease, amyotrophic lateral sclerosis, Huntington’s disease, cerebral ischemia, and acute spinal cord injury (ASCI), are closely related to autophagy. However, therapeutic strategies to manipulate autophagy have not yet been fully deciphered due to the limited knowledge of the molecular mechanisms underlying autophagy in these disorders.展开更多

However, the associated sequent problems are proportionally high. Almost two thirds of PROM are spontaneous, common risk factor young mother, multiple pregnancy, genital tract infection, previous preterm delivery. The complications range from induction of labour, caesarean section, fetal pulmonary morbidity and even mortality. Objectives of the Study: To identify and quantify the risk factors and complications of premature rupture of membrane in pregnant women in Benghazi, Libya, 2012. Material and Methods: 100 pregnant women diagnosed as PROM were examined for the physical signs. Detailed gynaecological and obstetric history was reported. Laboratory investigations included cervical swabs and posterior fornix swabs under aseptic conditions Drugs including types of antibiotics, Dexamethasone and tocolytics were also included. Results: The mean age of 100 patients was 28.9 years. Most of them, 66.1% of patients received antibiotis mostly Erythromycin. Dexamethasone was given for 32.1%. FTND accounted for 62% and PTND for 10% and Caesarean section was performed for 28%. The main indications for C/S were failed induction, in 50%, 11.8% were equally distributed between;macrosomia, previous scars, drained liquor, previous C/S, breech presentation. Only 1% of new born babies had complication. Conclusions and Recommendations: Further large studies should be done for more elaboration and analytical studies to quantify the strength of each risk factor. Strategy for management of PROM should be adopted for proper timing of induction, emergency caesarean intervention with ultimate goals of minimizing and or preventing maternal and fetal complications of disease.展开更多

The species had nu mbered over 2000 animals in early 1970s, but declined to no more than 1,000 anim als fragmented into perhaps 32 subpopulations in late 1990s as the result of num erous detrimental forces such as habitat shrinking, poaching and bamboo flowerin g. The mass flowering and followed die-off of bamboo played key roles in the dec lination of panda population in the past three decades. It trigged the starvatio n and following high mortality of giant pandas in 1970s over Min Mountains and i n 1980s across Qionglai Mountains in Sichuan Province. The situation of survivor ship is made worse by the fact that the panda habitat is fragmented into many sm all 'islands', each containing only a few pandas. Such small, isolated panda pop ulations are rendered even more vulnerable to extinction form threats such as ha bitat degradation, natural disaster, disease, and the deleterious effects of inb reeding. So restoring the panda habitat and reintroduction pandas to their histo rical habitat might be an important issue for protecting the giant panda in wild .展开更多
