  • Cardiovascular emergencies account for at least 30% of all medical emergencies. The impact of cardiovascular disease is felt in every hospital and every community. Whether you are drawn to critical care practice or not, you are bound to be confronted by acute cardiac events. Responding appropriately to cardiac emergencies requires a basic familiarity with cardiac anatomy and physiology, the ability to mobilize an advanced life support team, and the skills to perform cardiopulmonary resuscitation (CPR)....

  • Cardiovascular emergencies account for 30–40% of an acute medical workload that has grown inexorably over the last two decades. The same period has also witnessed unprecedented changes in the classification, investigation and treatment of acute cardiac problems, driven by advances in basic sciences, pharmacology and technology, but above all by a proliferating body of evidence from controlled trials.

  • Acute-care clinicians are well aware of the alphabetical “ABC” (airway, breathing, circulation) directive of resuscitation. This term has been widely disseminated through programs such as Advanced Trauma Life Support (ATLS) and Advanced Cardiac Life Support (ACLS). In fact, both courses have contributed significantly to improving awareness of resuscitation priorities required in managing patients rendered critically ill from trauma or cardiac events.

  • The process of ageing has resulted in the emergence of a new epidemiological scenario in the developing countries with high prevalence of degenerative diseases that act as a major cause of death and disability and lack of mobility (Smith and Bares, 1991, Zwi, 1999). There are evidences of unhealthy ageing from almost all the developing countries of Asia, Africa, and Latin America. Pelaez and and Palloni (1998) have concluded that there is a long-run health degeneration in the ageing societies of the Caribbean and Latin America with changing disease pattern.

  • Recently, Th17 cells were identified as a new subset of T helper cells unrelated to Th1 or Th2 cells. They are a subset of T helper cells characterized by IL-17 production, differentiated from naïve T cells in the presence of both transforming growth factor (TGF)-β and IL-6 in mice, and are implicated in the pathogenesis of experimental allergic encephalomyelitis (EAE) and collagen-induced arthritis (CIA) (Langrish et al. 2005).

  • The literature has pointed out to the relationship between obesity in youth and premature death due to endogenous causes of cardiac/metabolic origin. It is therefore fundamental to know how and when the risk factors for CMD begin to affect vascular function and structure, and particularly, how to detect them early in order to enable the development of truly primary preventive strategies.

  • The major pathogenic mechanism of poststreptococcal glomerulonephritis (PSGN) is an in situ immune complex formation due to deposition of streptococcal nephritogenic antigens, such as nephritis-associated plasmin receptor (NAPlr) and Streptococcal pyrogenic exotoxin B (SPE B). Both are capable of activating the alternate pathway of the complement cascade and enhance the expression of adhesion molecules. SPE B also stimulates the production of chemotactic cytokines. NAPlr was isolated from group A streptococcus and was shown to bind plasmin(ogen).

  • In the first approach, we divide our sample into two groups, based on each of the explanatory variables in turn, and calculate the median CGAP measure for each group. In some cases the demarcation between the two groups is clear: For example, economies may be classified as either an emerging market economy (EME) or not. For continuous variables, we use the median across the sample to divide the economies into two groups: economies where the explanatory variable exceeds the median are placed in group 1, and the remainder in group 0.

  • An equally important point is how the funds mobilised/owned by the companies are being utilised. In a study conducted at the ISID it was noticed that companies of different sizes extended loans to or invested in other enterprises in a big way. Such phenomenon is more prevalent in profit-making companies. Within the profit-making companies those who increased their borrowings invested relatively more than the rest. There is growing importance of group companies and non-marketable securities as also advances to group companies in such outside investments.

  • Genomics and other "omics” technologies have largely contributed to the identification and the development of biomarkers. Due to genetic causes of variability among individuals, genotyping and gene expression analysis are indeed key elements of the emergence of personalised medicine. However, genomic technologies have limitations (functional significance of genetic variants, false negatives, etc) and cannot encompass all approaches for the development of stratification biomarkers.

  • Unpublished data from Brigham and Women's Hospital Chest Pain Study, 1997–1999 Markers of myocardial injury are often obtained in the emergency department evaluation of acute chest discomfort. The most commonly used markers are creatine kinase (CK), CK-MB, and the cardiac troponins (I and T). Rapid bedside assays of the cardiac troponins have been developed and shown to be sufficiently accurate to predict prognosis and guide management.
