Hippocampal Functional Connectivity Patterns During Spatial Working Memory Differ In Right Versus Left Temporal Lobe Epilepsy., Gaelle Eve Doucet, Karol Osipowicz, Ashwini Sharan Md, Michael R Sperling, Joseph I Tracy

Gaelle Eve Doucet

Temporal lobe epilepsy (TLE), affecting the medial temporal lobe, is a disorder that affects not just episodic memory but also working memory (WM). However, the exact nature of hippocampal-related network activity in visuospatial WM remains unclear. To clarify this, we utilized a functional connectivity (FC) methodology to investigate hippocampal network involvement during the encoding phase of a functional magnetic resonance imaging (fMRI) visuospatial WM task in right and left TLE patients. Specifically, we assessed the relation between FC within right and left hippocampus-seeded networks, and patient performance (rate of correct responses) during the encoding phase of a block span WM …

Barriers And Facilitators For Colorectal Cancer Screening Practices In The Latino Community: Perspectives From Community Leaders, Ana Natale-Pereira, Jonnie Marks, Marielos Vega, Dawne Mouzon, Shawna Hudson, Debbie Salas-Lopez

Debbie Salas-Lopez MD, MPH

BACKGROUND: Colorectal cancer (CRC) is the second-leading cause of cancer-related death in the United States and the third most commonly diagnosed cancer among Latinos. While Latinos represent one of the fastest-growing ethnic groups in the United States, their participation in cancer prevention and treatment trials is low. METHODS: Thirty-six Latino community leaders participated in five focus groups that examined factors affecting CRC screening practices among Latinos. RESULTS: The top four barriers identified were low knowledge and awareness of CRC, language barriers, lack of insurance, and undocumented legal status. Additional barriers included seeking health care only when sick, fatalism, fear, denial …

Perspectives On Cancer Screening Among Latino Community Members And Internal Medicine Residents, Debbie Salas-Lopez, Dawne Mouzon, Jonnie Marks, Neil Kothari, Ana Natale-Pereira

Debbie Salas-Lopez MD, MPH

BACKGROUND: Latinos have lower rates of cancer screening, partially because of cultural beliefs that conflict with those of health care professionals. Moreover, established programs for training physicians in cultural competency often fail to incorporate input from the community.

METHODS: To explore beliefs about cancer and cancer screening among Latino community members and internal medicine residents. Three focus groups of Latino community members (n = 31) and one focus group of internal medicine residents (n = 9) were conducted to compare ideas regarding cancer and cancer screening.

RESULTS: We identified clear disconnects between residents and Latino community members regarding their understandings …

National Trauma Institute Prospective Evaluation Of The Ventilator Bundle In Trauma Patients: Does It Really Work?, Martin A. Croce Md, Karen J. Brasel Md, Mph, Raul Coimbra Md, Phd, Charles A. Adams Jr, Md, Preston R. Miller Md, Michael D. Pasquale Md, Facs, Fccm, Chanchai S. Mcdonald Phd, Somchan Vuthipadadon Phd, Timothy C. Fabian Md, Elizabeth A. Tolley Phd

BACKGROUND: Since its introduction by the Institute for Healthcare Improvement, the ventilator bundle (VB) has been credited with a reduction in ventilator-associated pneumonia (VAP). The VB consists of stress ulcer prophylaxis, deep venous thrombosis prophylaxis, head-of-bed elevation, and daily sedation vacation with weaning assessment. While there is little compelling evidence that the VB is effective, it has been widely accepted. The Centers for Medical and Medicaid Services has suggested that VAP should be a "never event" and may reduce payment to providers. To provide evidence of its efficacy, the National Trauma Institute organized a prospective multi-institutional trial to evaluate the …

Comparison Of Insulin Infusion Protocols Targeting 110-140 Mg/Dl In Patients After Cardiac Surgery., Vasudev Magaji, Shriddha Nayak, Amy Donihi, Lauren Willard, Srinivasa Jampana, Parachur Nivedita, Raymond Eder, Jann Johnston, Mary Korytkowski

Vasudev G Magaji MD, MS

BACKGROUND: Continuous intravenous insulin infusion (CII) following coronary artery bypass graft (CABG) surgery reduces postoperative complications and hospitalization duration. Because of limited data evaluating outcomes of CII with revised glycemic targets (110-140 mg/dL) in cardiac surgery, this study compared efficacy and safety of two different CII protocols having revised targets. SUBJECTS AND METHODS: This is a retrospective study comparing two different protocols between August 2009 and March 2010. Protocol 1 consists of four algorithms, and Protocol 2 is a table to adjust CII. Blood glucose (BG) and CII rates were recorded for 48 h postoperatively or CII discontinuation. Efficacy was …

Angiographic Recognition Of Ostial Left Main Coronary Artery Stenosis: Case Report., R M Macmillan, Bruce Feldman, V Maranhao

Bruce A. Feldman DO

Ostial left main coronary stenosis has a poor prognosis and increased mortality rate with coronary arteriography. Due to its anatomic location, visualization of the stenosis may be difficult. A high index of suspicion based upon only a few signs should prompt the physician to perform certain maneuvers to obtain the correct diagnosis. Four illustrative cases are presented and discussed.

Addressing The Controversy Of Rate-Versus-Rhythm Control In Atrial Fibrillation, Tahmeed Contractor, Vadim Levin, Ravi Desai, Francis E Marchlinski

Vadim A Levin MD

Atrial fibrillation is the most common sustained cardiac arrhythmia and significantly increases patient risk of stroke, cardiomyopathy, and mortality. Rate versus rhythm control as the "best" treatment strategy remains an issue of considerable, ongoing debate. A multitude of clinical trials have compared the 2 strategies and have not shown any benefit of one approach over the other. However, the trials were conducted in specific subgroups of patients and demonstrated low success rates with antiarrhythmic drug (AAD) therapy and a high incidence of adverse AAD effects. Sub-analyses of the trials have confirmed that successful rhythm control with sinus rhythm restoration is …
