  • Physical Activity Physical activity is associated with a decreased risk of colon and breast cancer. A variety of mechanisms have been proposed. However, such studies are prone to confounding factors such as recall bias, association of exercise with other health-related practices, and effects of preclinical cancers on exercise habits (reverse causality). Recommending adults to engage in at least 30 min of vigorous activity for ≥3 days a week is good health advice, though its effects on cancer incidence are unproven.

  • Flow cytometry is a technology that simultaneously measures and analyses multiple physical characteristics of single particles, usually cells, as they flow in a fluid stream through a beam of light. The properties measured include a particle’s relative size (represented by forward angle light scatter), relative granularity or internal complexity (represented by right-angle scatter), and relative fluorescence intensity.

  • With advances in the management of acute myocardial infarction (AMI) the incidence of mechanical complications continues to decline. Nevertheless, when they occur, unfortunately, despite similar advances and growing experiences in the surgical management of these problems, morbidity and mortality remain high. Post-myocardial infarction ventricular septal defects (PI-VSD) have fascinated and challenged clinicians for years.

  • Adenoviruses have been recognized as opportunistic and significant viral pathogens in immunocompromised patients such as recipients of hematopoietic stem cells or other solid organs treated with immunosuppressive agents, and among patients with acquired immunodeficiency syndrome. These patients are incapable of developing a normal immune response. Reactivation of adenoviruses in the impaired immunological response leads to acute or persistent infections with high morbidity or even mortality in these patients.

  • Historically, up to 5% of all myocardial infractions were associated with mechanical complications such free-wall rupture, papillary muscle rupture, and PI-VSD (Agnihotri, 2008). With current treatment algorithms that advocate early and aggressive attempts at revascularization of the acute ischemic myocardial – such as thrombolytic therapy, early percutanous interventions with coronary stenting (PCI), and, less frequently, emergent coronary artery bypass surgery (CABG) – the overall incidence has dropped significantly.

  • The Railway Accident Investigation Unit (RAIU) is a functionally independent investigation unit within the Railway Safety Commission (RSC). The purpose of an investigation by the RAIU is to improve railway safety by establishing, in so far as possible, the cause or causes of an accident or incident with a view to making recommendations for the avoidance of accidents in the future, or otherwise for the improvement of railway safety. It is not the purpose of an investigation to attribute blame or liability.

  • What, then, makes for the distinction between mere experience and an experience? First, there are the related issues of unity and closure. Mere experience, Dewey notes, is continuous, often ‘inchoate’, and characterized by ‘distraction and dispersion’ (p. 35). In mere experience, ‘we are not concerned with the connection of one incident with what went before and what comes after. … Things happen, but they are neither definitely included nor decisively excluded; we drift’ (p. 40). ...

  • For this paper, we have examined the concept of an investigation to determine what is required. The result is an event-based framework that can be used to develop hypotheses and answer questions about an incident or crime. Hypotheses are developed by collecting objects that may have played a role in an event that was related to the incident. Once the objects are collected as evidence, the investigator can develop hypotheses about previous events at the crime scene.

  • Some environments have developed policies and laws that forbid certain events from occurring. An incident is an event or sequence of events that violate a policy and more specifically, a crime is an event or sequence or events that violate a law. In particular, a digital incident is one or more digital events that violate a policy. In response to an incident or crime, an investigation may begin. An investigation is a process that develops and tests hypotheses to answer questions about events that occurred.

  • Good logging is important for real-time incident detection and after-the-fact auditing. By religiously watching your log file, you will often get warnings that an outage is about to occur or that an attacker is analyzing your network for vulnerabilities. This allows you to take action to correct or prevent the problem. Log files also provide an audit trail for determining what went wrong or what an attacker accomplished.

  • In this module, students explore auditing and incident response as means for detecting and responding to security incidents. When an attack happens, the key to limiting damage is early detection and a rapid and orderly response. Auditing is an important tool to help students detect network abnormalities that may indicate attacks. An incident response procedure is a series of steps that students design in advance to guide their organization during a security incident.

  • Data were included from individuals participating in a prospective study of 2,126 Medicare recipients, 65 years and older, residing in a single community in Northern Man- hattan. Each person received the same medical, neurological and neuropsychological evaluations at regular intervals. The cohort was followed over a 7-year period beginning in 1992. Three follow-up examinations took place at 20-month in- tervals after the baseline interview. Over the study period, the annual mortality rate has been 8.

  • The first population-based cancer registry was set up in Hamburg (Germany) in 1926. Three nurses visited hospitals and medical practitioners in the city at regular intervals. They recorded the names of new cancer patients and transferred data to a central index in the health department. This index was compared once a week with official death certificates. Other popu- lation-based cancer registries were set up in subsequent decades, so that by 1955, almost twenty had been established in various countries....

  • To help inform prevention and control strategies, research efforts have been directed at establishing the likely contributors to this rise in campylobacteriosis incidence. Consistent with international findings (6–8), New Zealand investigations implicated poultry meat as a significant source of foodborne sporadic campylobacteriosis (9–13). A relatively small case–control study in Christchurch in 1992–1993 reported several poultry-associated risk factors, including consumption of undercooked poultry (10).

  • Sepsis is a complex syndrome characterized by systemic inflammation in response to infection. It is a significant health problem with an estimated 750,000 new cases in the USA annually [1]. It is also the third leading cause of death in developed countries, equalling the number of fatalities from acute myocardial infarction. The incidence of sepsis has increased in recent decades and is predicted to continue to rise. The high sepsis-related mortalities and the burden on healthcare systems means there is an urgent need to improve the diagnosis and management of sepsis patients....

  • By 1991, the NHSBSP was inviting over one million women a year for screening. In the autumn of that year, a controversy erupted when the value of breast self examination was questioned by the then Chief Medi- cal Officer. Over the next three weeks, the policy of breast awareness, which had been under development, was hastily polished and delivered. The Department of Health then released the first figures from the breast screening programme showing that it was finding a high rate of cancers and appeared to be on target.
