Testing of the late-ordovician Pre-GICE warm water carbonate hypothesis in Alabama

The Guttenberg Carbon Isotope Excursion (GICE) (uppermost Sandbian-lower Katian, Late Ordovician) has been suggested to represent the transition from a Cambrian-Ordovician greenhouse world to Late Ordovician icehouse world. This transition is thought to coincide with a proposed shift from deposition of warm water carbonate rocks to cool water carbonate rocks in the North American midcontinent. We used oxygen isotopes (d18O) of conodonts to test the idea that the rocks below the GICE interval represent a consistently warm environment. Conodonts were isolated from samples of the Chickamauga Group collected at the Tidwell Hollow section in Blount County, AL, from the Red Mountain Expressway section in Birmingham, AL, and from Dickeyville, WI. These successions underlie strata that biostratigraphically correlate with the GICE interval. Conodonts at Tidwell Hollow include Appalachignathus sp. and Phragmodus flexuosus near the base of the Chickamauga Group and Oulodus oregonia and Aphelognathus kimmswickensis near its top. These taxa indicate that the interval studied ranges from the Plectodina aculeata Zone to at least the Plectodina tenuis Zone, spanning from below and through the GICE. Conodonts from the Red Mountain Expressway section were collected only to 22m below the Millbrig K-bentonite, where Belodina compressa and Curtognathus spp. dominate the fauna. At 10m below the Millbrig, Polyplacognathus ramosus occurs and the top of the section contains a fauna that includes Phragmodus undatus and Icriodella superba. Results indicate that the sampled interval ranges from the Belodina compressa Zone to the Phragmodus undatus Zone, an interval which is below and up to the GICE. The conodont d18O values indicate that the rocks below the GICE in Alabama represent a consistently warm environment throughout the Chickamauga Group below the Millbrig K-bentonite Bed, supporting the idea that the pre-GICE environment was relatively stable, and that the GICE, along with the changes in d18O in the GICE interval, could reflect a perturbation in the Ordovician climate

Improvement in systolic function in left ventricular non-compaction cardiomyopathy: A case report

AbstractThis is a case of a 48-year-old man who presented with a pulmonary embolism and was found to have left ventricular non-compaction cardiomyopathy. Initial echocardiograms demonstrated prominent apical trabeculations with reduced biventricular function. These findings were further confirmed and characterized by cardiac magnetic resonance imaging. He met all major criteria used to identify left ventricular non-compaction cardiomyopathy. He underwent medical management for heart failure and during follow-up was noted to have significant improvement in left ventricular systolic function and symptoms. While most management attention is focused on rhythm disturbances or embolic risk, particular attention should also be exercised to ensure that heart failure medical therapy is optimized. While many with left ventricular non-compaction cardiomyopathy have irreversible dysfunction, this case highlights that there may be some who will respond well to aggressive medical therapy. The diagnosis and medical management of left ventricular non-compaction cardiomyopathy are reviewed in light of our patient and his clinical course.<Learning objective: Historically, left ventricular non-compaction cardiomyopathy (LVNC) has been associated with significant morbidity and mortality. Discussion often focuses on sudden cardiac death and prevention of embolisms. Many of the initial reports and case series were written in an era when standard medical therapy for congestive heart failure was not yet defined. While many do not respond as this case did, this case emphasizes that optimal medical therapy can make a substantial difference, even for LVNC.

Perceived impacts of a Public Health Training Center field placement program among trainees: findings from a small group externship experience

There is heightened interest in identifying the impact of the federally funded Public Health Training Center (PHTC) program. Although evaluation studies have been conducted of public health training in general, evaluations of PHTC programs are rare. Field placement components are congressionally mandated requirements of PHTCs. Field placements are typically intensive, supervised externships for students to gain public health experience with local health departments or non-profit organizations. We have found no published evaluations of PHTC field placement components. This may be because of their small size and unique nature. We designed and evaluated a 200-h field placement program at an established PHTC. The evaluation included pre/post surveys measuring public health core competencies, and post-experience interviews.We found significant increases in three competency domains among trainees: policy development and program planning, communication skills, and community dimensions of practice. These outcomes contribute to evidence based on the efficacy of PHTC field placement programs, and underscore their role in public health training
