Rural health in the Progressive Era: revisiting the hookworm intervention in the American South.

Objective: In this study, we investigated Progressive Era public health interventions and connected two subsequent efforts to improve outcomes in the American South: the Rockefeller Sanitary Commission's hookworm eradication efforts in the early 1910s and investments in local health infrastructure between the 1910s and the 1930s. We tested whether hookworm eradication had the largest effects in areas that invested in public health and whether county health organizations-cooperative public-private institutional arrangements-impacted the Rockefeller Sanitary Commission program's success. Materials and Methods: The methods used to measure the effects involved estimation of difference-in-difference and triple-difference models across the geographic samples of the Rockefeller Sanitary Commission's surveyed area, the American South, and the United States. Material on hookworm infection rates and activities by the Rockefeller Sanitary Commission is obtained from the Rockefeller Foundation Annual Reports. Material on the activities, spending, and duration of the different county health organizations is obtained from the Public Health Service Bulletin 222 titled, "A history of county health organizations in the United States: 1908-1933". Results: By comparing similar cooperative and independent county health organizations in the American South with the rest of the United States, we find that cooperative efforts are generally important and strengthen the Rockefeller Sanitary Commission's impact on human capital outcomes in the American South. Simultaneously, independent county health organizations produced negative or non-significant effects. Conclusion: The Rockefeller Sanitary Commission is important in guiding local health efforts. Our results are robust in both the short and long runs. This study sheds light on the effectiveness of public-private partnerships in rural public health during the Progressive Era.

Direct Laryngoscopy and Endotracheal Intubation Complicated by Anterior Tracheal Laceration Secondary to Protrusion of Preloaded Endotracheal Tube Stylet.

Tracheal wall disruption is a rare complication of endotracheal intubation, typically occurring in the posterior (membranous) trachea lacking cartilaginous support. We present the case of a 68-year-old man who developed an anterior tracheal tear after routine endotracheal intubation, most likely occurring secondary to protrusion of a factory-preloaded stylet beyond the distal orifice of the endotracheal tube. Tracheal disruption should be considered in any patient with subcutaneous emphysema and respiratory distress after tracheal extubation and confirmed with bronchoscopy. Conservative management may be appropriate for those with small tears, hemodynamic stability, and the ability to isolate the tear from positive pressure ventilation.

Principles of cerebral oxygenation and blood flow in the neurological critical care unit.

Cerebrovascular disease and trauma are leading causes of death in the United States. In addition to the initial insult to the brain, disturbances of cerebral oxygenation and metabolism underlie many of the secondary pathophysiological processes that increase both morbidity and mortality. Therefore, researchers and clinicians have sought to obtain a more thorough understanding of the physiological and biochemical principles of cerebral oxygenation and metabolism. New technologies capable of offering continuous and quantitative assessment of cerebral oxygenation may improve clinical outcomes. In this article, we review the physiological principles of cerebral metabolism, cerebral blood flow and their metabolic coupling, and cerebral oxygenation, with particular emphasis on variables that could be monitored and managed in an intensive care unit setting.
