The finances of academic medical centers (AMCs) are complex and rapidly evolving. This financial environment can have important effects on faculty expectations, compensation, and the work environment. This article describes the commonly used concepts and models related to financial decision-making in Pulmonology and Critical Care divisions across AMCs in the United States. ⋯ Measurements of productivity within education have been less codified, but some centers are attempting to create educational relative value units similar to those used in clinical productivity. In summary, faculty should understand basic concepts of finances. This knowledge includes a common set of terms and concepts that can help all faculty understand basic financial considerations in their work and lead to success for their divisions.

Phenotypic sub-types of obstructive sleep apnea: a challenge and opportunity for precision medicine.
Current strategies for the management of OSA reflect a one-size-fits-all approach. Diagnosis and severity of OSA are based on the apnea-hypopnea index and treatment initiated with CPAP, followed by trials of alternatives (eg, oral appliances) if CPAP "fails." This approach does not consider the heterogeneity of individuals with OSA, reflected by varying risk factors, pathophysiological causes, clinical manifestations, and consequences. Recently, studies using analytic approaches such as cluster analysis have taken advantage of this heterogeneity to identify OSA phenotypes, or subtypes of patients with unique characteristics, that may enable more personalized approaches to prognostication and treatment. ⋯ This review summarizes the findings from recent cluster analysis studies in sleep apnea and synthesizes common themes to describe the potential role (and limitations) of phenotypic subtypes in precision medicine for OSA. It also highlights future directions, including linking of phenotypes to clinically relevant outcomes, rigorous and transparent assessment of phenotype reproducibility, and need for tools that categorize patients into subtypes, to prospectively validate phenotype-based prognostication and treatment approaches. Finally, we highlight the critical need to include women and more racially/ethnically diverse populations in this area of research if we are to leverage the heterogeneity of OSA to improve patient lives.

Although there is ongoing debate regarding the impact of early postnatal exposure to antibiotics on the development of asthma, the possibility that antibiotic exposure may impair lung function has not previously been examined. Furthermore, it is unclear if specific types of antibiotics may have a greater effect, or if children with genetic mutations in the oxidative stress response glutathione S-transferase (GST) superfamily may be at greater risk. ⋯ Increasing exposure to oral antibiotics in early postnatal life was not associated with reduced lung function in children with a family history of allergic diseases. Although unwarranted use of antibiotics in children should be minimized, concerns regarding long-term lung health should not be a driving influence for this rationalization of use.

Destombes-Rosai-Dorfman disease (RDD) is a rare multisystemic histiocytosis. Pulmonary involvement during RDD has been poorly described. The goal of this study was to examine the clinical presentations, radiological features, and outcomes of 15 patients with RDD and lung involvement. ⋯ Pulmonary involvement in RDD is rare, proteiform, and sometimes severe. The MEK inhibitor cobimetinib can lead to dramatic responses.

Initial fluid resuscitation volume for sepsis is controversial, particularly in patients at high baseline risk for complications. This study was designed to assess the association between 30 mL/kg crystalloids and intubation in patients with sepsis or septic shock and heart failure, end-stage renal disease, or cirrhosis. ⋯ No differences were detected in the incidence of intubation in patients with sepsis and cirrhosis, end-stage renal disease, or heart failure who received guideline-recommended fluid resuscitation with 30 mL/kg compared with patients initially resuscitated with a lower fluid volume.
