This chapter provides a summary of the landmark study “Comparison of 8 versus 15 days of antibiotic therapy for ventilator-associated pneumonia in adults: a randomized trial.” In adult patients with ventilator-associated pneumonia (VAP), is treatment with an 8-day course of antimicrobials as effective as a 15-day course? Starting with that question, the chapter describes the basics of the study, including funding, study location, who was studied, how many patients, study design, study intervention, follow-up, endpoints, results, and criticism and limitations. The chapter briefly reviews other relevant studies and information, discusses implications, and concludes with a relevant clinical case. In ICU patients who develop microbiologically proven VAP, an 8-day antimicrobial course is not inferior to a 15-day course with respect to all-cause mortality or recurrence of pulmonary infection. However, these findings may not apply to patients who are immunocompromised, and shorter or longer duration of antibiotics may sometimes be indicated.

This chapter provides a summary of the landmark study known as a protocol of no sedation for critically ill patients receiving mechanical ventilation: a randomized trial. Can duration of mechanical ventilation be reduced with a protocol of no sedation versus daily interruption of sedation? Starting with that question, it describes the basics of the study, including funding, study location, who was studied, how many patients, study design, study intervention, follow-up, endpoints, results, and criticism and limitations. The chapter briefly reviews other relevant studies and information, discusses implications, and concludes with a relevant clinical case. Understanding that not all patients receiving mechanical ventilation require sedation is an important first step to determining the best regimen.

With this in mind, it describes the basics of the study, including funding, study location, who was studied, how many patients, study design, study intervention, follow-up, endpoints, results, and criticism and limitations. The chapter briefly reviews other relevant studies and information, discusses implications, and concludes with a relevant clinical case.

This chapter summarizes a landmark study in treatment of gastroesophageal (GE) junction tumors. Should an anatomically based classification scheme of GE tumors define the appropriate treatment approach for these tumors? Starting with that question, it describes the basis of the study, including funding, year study began, year study was published, study location, who was studied, who was excluded, how many patients, study design, study intervention, follow-up, endpoints, results, and criticism and limitations. The chapter briefly reviews other relevant studies and information, gives a summary and discusses implications, and concludes with a relevant clinical case involving possible gastrectomy and esophagectomy.

This chapter provides a summary of the landmark study known as the B-06 trial, which compared total mastectomy versus breast-conserving therapy (i.e., lumpectomy) for treating women with invasive breast cancer. Do all women with invasive breast cancer require a total mastectomy, or is breast conserving therapy (i.e., lumpectomy) appropriate in some women? Starting with that question, it describes the basics of the study, including funding, year study began, year study was published, study location, who was studied, who was excluded, how many patients, study design, study intervention, follow-up, endpoints, results, and criticism and limitations. The chapter briefly reviews other relevant studies and information, gives a summary and discusses implications, and concludes with a relevant clinical case involving total mastectomy versus lumpectomy.

This chapter provides a summary of a landmark study on schizophrenia. The question studied was “In patients identified clinically to be at high risk for psychosis, which variables (or their combinations) best predict conversion to schizophrenia or another psychotic disorder?” Starting with that question, it describes the basics of the study, including funding, study location, who was studied, how many patients, study design, study intervention, follow-up, endpoints, results, and criticism and limitations. This study demonstrates that presence of some characteristics can better prognosticate conversion of a prodromal state to a psychotic disorder.
