Health care–associated infections are important, often preventable, causes of poor outcomes and unnecessary costs of medical care.1 To address this public health problem, professional societies, quality-improvement organizations, accrediting bodies, and federal advisory committees and agencies have issued guidelines and recommendations aimed at preventing these infections.2
2011 Apr 14 - Veterans Affairs Initiative to Prevent Methicillin-Resistant Staphylococcus aureus Infections
Health care–associated infections with methicillin-resistant Staphylococcus aureus (MRSA) have been an increasing concern in Veterans Affairs (VA) hospitals.
Intensive care units (ICUs) are high-risk settings for the transmission of methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococcus (VRE).
The acute respiratory distress syndrome (ARDS) is commonly a cause for admission to the intensive care unit (ICU) and for mechanical ventilation. Within the past decade, research has shown not only that the need for acute supportive care is extensive and protracted, but also that the arc of recovery can be long, and the burden for survivors of ARDS is actually psychological and neuromuscular dysfunction.1,2
There have been few detailed, in-person interviews and examinations to obtain follow-up data on 5-year outcomes among survivors of the acute respiratory distress syndrome (ARDS).
Patients with a variety of intracranial disorders — including traumatic brain injury, stroke, subarachnoid hemorrhage, intracerebral hemorrhage, and brain tumors — often present with a progressive increase in intracranial pressure, leading to clinical deterioration and ultimately to death.
It is unclear whether decompressive craniectomy improves the functional outcome in patients with severe traumatic brain injury and refractory raised intracranial pressure.

The effects of thromboprophylaxis with low-molecular-weight heparin, as compared with unfractionated heparin, on venous thromboembolism, bleeding, and other outcomes are uncertain in critically ill patients.
Loop diuretics are an essential component of therapy for patients with acute decompensated heart failure, but there are few prospective data to guide their use.
Mammals have oxygen-sensing mechanisms that help them adapt quickly to hypoxia by increasing respiration, blood flow, and survival responses. If an inadequate supply of oxygen persists, additional mechanisms attempt to restore oxygenation or help the body adapt to hypoxia.1 These other mechanisms rely on oxygen-sensing prolyl hydroxylases (PHDs), which hydroxylate prolines in the alpha subunit of the hypoxia-inducible transcription factor (HIF). This transcription factor is a heterodimer with two subunits: HIF-1α or HIF-2α and HIF-1β (or aryl hydrocarbon receptor nuclear translocator [ARNT] protein). HIF-1α is ubiquitous, whereas HIF-2α is restricted to certain tissues.1
Arterial Puncture for Blood Gas Analysis Overview Radial arterial puncture for arterial blood gas analysis is a common procedure performed in medicine. It is a fundamental skill that all medical trainees need to acquire. This video will review radial arterial puncture in the adult population. Indications Puncture of the radial artery is the preferred method of obtaining an arterial blood sample for blood gas analysis.
Approximately 1.5 million patients undergo percutaneous coronary intervention (PCI) in the United States every year.1 Depending on local practices and the diagnostic criteria used, 5 to 30% of these patients (75,000 to 450,000) have evidence of a periprocedural myocardial infarction.2,3 At the higher estimate, the incidence of these events is similar to the annual rate of major spontaneous myocardial infarction.1
Since 1996, the incidence of Clostridium difficile infection has more than doubled. Some estimates suggest that there may be up to 3 million cases each year in the United States. If that statistic is correct, it would make C. difficile infection the most common bacterial cause of diarrhea in the United States. With the rising incidence, we are seeing higher mortality associated with the disease, related to at least two factors: increasing virulence of the C. difficile strains and increasing host vulnerability.
Clostridium difficile infection is a serious diarrheal illness associated with substantial morbidity and mortality. Patients generally have a response to oral vancomycin or metronidazole; however, the rate of recurrence is high. This phase 3 clinical trial compared the efficacy and safety of fidaxomicin with those of vancomycin in treating C. difficile infection.
The incidence of ventricular fibrillation or pulseless ventricular tachycardia as the first recorded rhythm after out-of-hospital cardiac arrest has unexpectedly declined. The success of bystander-deployed automated external defibrillators (AEDs) in public settings suggests that this may be the more common initial rhythm when out-of-hospital cardiac arrest occurs in public. We conducted a study to determine whether the location of the arrest, the type of arrhythmia, and the probability of survival are associated.
An 88-year-old man with long-standing obstructive lung disease was admitted to the intensive care unit with pneumonia and acute respiratory failure requiring mechanical ventilation. He was noted to have a symmetric, scaly, sunburn-like, hyperpigmented rash extending from his hands to a clearly demarcated border midway up the arm, suggesting a photosensitive distribution in a patient accustomed to wearing short sleeves.
Necrotizing enterocolitis is among the most common and devastating diseases in neonates. It has also been one of the most difficult to eradicate1 and thus has become a priority for research.2 Conditions closely resembling necrotizing enterocolitis were described before the 1960s, but the entity was not widely recognized until after the advent of modern neonatal intensive care.1
The midazolam dose of 0.15 mg per kilogram of body weight per hour described in the article by Holzer (Sept. 23 issue)1 and in other articles on therapeutic hypothermia2 is very similar to the recommended dose of midazolam used to adapt critically ill patients without neurologic problems to mechanical ventilation.3
In the United States, nearly 60,000 patients per day receive general anesthesia for surgery.1 General anesthesia is a drug-induced, reversible condition that includes specific behavioral and physiological traits — unconsciousness, amnesia, analgesia, and akinesia — with concomitant stability of the autonomic, cardiovascular, respiratory, and thermoregulatory systems.2 General anesthesia produces distinct patterns on the electroencephalogram (EEG), the most common of which is a progressive increase in low-frequency, high-amplitude activity as the level of general anesthesia deepens3,4 (Figure 1). How anesthetic drugs induce and maintain the behavioral states of general anesthesia is an important question in medicine and neuroscience.6 Substantial insights . . .

In the article by Lazarus (Aug. 19 issue),1 the author provides a comprehensive and balanced review of the emergency treatment of asthma but does not discuss the controversy around the use of epinephrine for acute severe asthma exacerbations.2
