Observational Study
Risk factors associated with potentially antibiotic-resistant pathogens in community-acquired pneumonia.
To identify pathogens that require different treatments in community-acquired pneumonia (CAP), we propose an acronym, "PES" (Pseudomonas aeruginosa, Enterobacteriaceae extended-spectrum β-lactamase-positive, and methicillin-resistant Staphylococcus aureus). ⋯ PES pathogens are responsible for a small proportion of CAP, resulting in high mortality. These pathogens require a different antibiotic treatment, and identification of specific risk factors could help to identify these microbial etiologies.

The American Thoracic Society (ATS), in collaboration with George Mason University, surveyed a random sample of ATS members to assess their perceptions of, clinical experiences with, and preferred policy responses to climate change. An e-mail containing an invitation from the ATS President and a link to an online survey was sent to 5,500 randomly selected U. S. members; up to four reminder e-mails were sent to nonrespondents. ⋯ A larger majority anticipated seeing these climate-related health impacts in the next 2 decades. Respondents indicated that physicians and physician organizations should play an active role in educating patients, the public, and policy makers on the human health effects of climate change. Overall, ATS members are observing that human health is already adversely affected by climate change and support responses to address this situation.

Stakeholders seek to monitor processes and outcomes of care among patients with sepsis, but use of administrative data for sepsis surveillance is controversial. Prior studies using only principal diagnoses from claims data have shown a trend of rising sepsis incidence with falling infection incidence, implying that administrative data are inaccurate for sepsis surveillance. ⋯ Sepsis claims are increasing at a greater rate than infection claims but are not inversely related. Trends in sepsis are similar to trends in infection cases requiring mechanical ventilation. Further studies should seek to identify the optimal algorithms to identify sepsis within administrative data and explore potential mechanisms for the increasing incidence of infection and sepsis in the United States.

Observational Study
A population-based observational study of intensive care unit-related outcomes. With emphasis on post-hospital outcomes.
Many studies of critical illness outcomes have been restricted to short-term outcomes, selected diagnoses, and patients in one or a few intensive care units (ICUs). ⋯ Post-hospital medical resource use among ICU survivors is substantial, although similar to that after non-ICU hospitalization. Although the fraction of survivors unable to live independently was small, a larger fraction required home care services. Identifying Post-hospital supports needed by ICU survivors can be useful for policy makers and others responsible for healthcare planning.

Lung carcinoma diagnosis on tissue biopsy can be challenging because of insufficient tumor and lack of architectural information. Optical coherence tomography (OCT) is a high-resolution imaging modality that visualizes tissue microarchitecture in volumes orders of magnitude larger than biopsy. It has been proposed that OCT could potentially replace tissue biopsy. ⋯ Although these results are encouraging, they indicate that OCT cannot replace histology in the diagnosis of lung carcinomas. However, OCT has potential to aid in diagnosing lung carcinomas as a complement to tissue biopsy, particularly when insufficient tissue is available for pathology assessment.
