A body of knowledge exists to suggest an association between nurse staffing and adverse patient outcomes. Hugonnet and colleagues add further evidence by linking nurse staffing to late-onset ventilator-associated pneumonia. Discussed are a number of concerns surrounding the analytic component of this study, including the construction of variables and the statistical models. The authors' estimation that hospitals maintaining a nurse-to-patient ratio above 2.2 could decrease the risk of health care associated infections is based on findings that are potentially biased and unrealistic.

Number needed to treat = six: therapeutic hypothermia following cardiac arrest--an effective and cheap approach to save lives.
In 2005, the European Resuscitation Council (ERC) guidelines stated: Unconscious adult patients with spontaneous circulation after out-of-hospital ventricular fibrillation cardiac arrest should be cooled to 32 to 34 degrees C for 12 to 24 hours. Patients with cardiac arrest from a non-shockable rhythm, in-hospital patients and children may also benefit from hypothermia. There is no argument to wait. We have to treat the next unconscious cardiac arrest patient with hypothermia.

Mechanotransduction holds the underlying mechanisms of ventilator-induced lung injury. Research on this subject, however, could be difficult for clinicians, especially when results are controversial. A recent study by Li and co-workers is used as an example, to explain how to critically read literatures related to basic science and how to understand the limitation of experimental studies.

Ethics roundtable debate: withdrawal of tube feeding in a patient with persistent vegetative state where the patients wishes are unclear and there is family dissension.
The decision to withdraw or withhold life supporting treatment in moribund patients is difficult under any circumstances. When the patient becomes incompetent to clarify their wishes regarding continued maintenance in long-term facilities, surrogates sometimes cannot agree, further clouding the issue. We examine a case where the State's interests come into play, forcing a controversial resolution.
