Alternative Surgical Approach To Repairing A Giant Sinus Of Valsalva Aneurysm, Vincenzo Giambruno, Cristina Cucchietti, Calogera Pisano, Jonathan Hyde Feb 2016

Alternative Surgical Approach To Repairing A Giant Sinus Of Valsalva Aneurysm, Vincenzo Giambruno, Cristina Cucchietti, Calogera Pisano, Jonathan Hyde

The Texas Heart Institute Journal

We report our method of surgically repairing an unruptured giant aneurysm of the right coronary sinus of Valsalva, a lesion that caused moderate aortic regurgitation but no symptoms in a 61-year-old woman. We excised the aneurysm, reconstructed the right sinus of Valsalva with use of a patch, performed mechanical aortic valve replacement directly through the excised aneurysm's cavity, and constructed a single bypass graft to the right coronary artery. The patient was discharged from the hospital after 5 days. Twelve months postoperatively, her clinical and echocardiographic results were normal, and she was doing well. To our knowledge, our surgical approach …

Aortic Dissection Caused By Percutaneous Coronary Intervention: 2 New Case Reports And Detailed Analysis Of 86 Previous Cases, Priyank Shah, Sharad Bajaj, Fayez Shamoon

The Texas Heart Institute Journal

Aortic dissection, a rare sequela of percutaneous coronary intervention, can be fatal when it is not recognized and treated promptly. Treatment varies from conservative management to invasive aortic repair and revascularization. We report the cases of 2 patients whose aortic dissection was caused by percutaneous coronary intervention. In addition, we present detailed analyses of 86 previously reported cases. Aortic dissection was most often seen during intervention to the right coronary artery (in 76.7% of instances). The 2 most frequently reported causes were catheter trauma (in 54% of cases) and balloon inflation (in 23.8%). The overall mortality rate was 7.1%. We …

Brain and Mind Institute Researchers' Publications

INTRODUCTION: The mildly invasive 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) is a well-established imaging technique to measure 'resting state' cerebral metabolism. This technique made it possible to assess changes in metabolic activity in clinical applications, such as the study of severe brain injury and disorders of consciousness.

OBJECTIVE: We assessed the possibility of creating functional MRI activity maps, which could estimate the relative levels of activity in FDG-PET cerebral metabolic maps. If no metabolic absolute measures can be extracted, our approach may still be of clinical use in centers without access to FDG-PET. It also overcomes the problem of recognizing individual …

Post-traumatic stress disorder (PTSD) is characterized by altered functional connectivity of the amygdala complexes at rest. However, amygdala complex connectivity during conscious and subconscious threat processing remains to be elucidated. Here, we investigate specific connectivity of the centromedial amygdala (CMA) and basolateral amygdala (BLA) during conscious and subconscious processing of trauma-related words among individuals with PTSD (n = 26) as compared to non-trauma-exposed controls (n = 20). Psycho-physiological interaction analyses were performed using the right and left amygdala complexes as regions of interest during conscious and subconscious trauma word processing. These analyses revealed a differential, context-dependent responses by each amygdala …

Journal Articles: Epidemiology

While most ecological studies have shown that higher levels of point-of-sale (POS) cigarette marketing are associated with larger proportions of residents from lower socioeconomic and minority backgrounds in neighborhoods, there are no studies that examine individual-level social disparities in exposure to POS cigarette marketing among smokers in the United States. Our aim was to examine these disparities in a Midwestern metropolitan area in the United States. We conducted a telephone survey to collect data on 999 smokers. Cigarette marketing was measured by asking respondents three questions about noticing advertisements, promotions, and displays of cigarettes within their respective neighborhoods. The questions …

Internal Medicine Faculty Publications

Rhodococcus equi is an unusual zoonotic pathogen that can cause life-threatening diseases in susceptible hosts. Twelve patients with R. equi infection in Kentucky were compared to 137 cases reported in the literature. Although lungs were the primary sites of infection in immunocompromised patients, extrapulmonary involvement only was more common in immunocompetent patients (P > 0.0001). Mortality in R. equi-infected HIV patients was lower in the HAART era (8%) than in pre-HAART era (56%) (P > 0.0001), suggesting that HAART improves prognosis in these patients. Most (85–100%) of clinical isolates were susceptible to vancomycin, clarithromycin, rifampin, aminoglycosides, ciprofloxacin, and imipenem. …

OBJECTIVE: Patients using U-500 regular insulin are severely insulin resistant, requiring high doses of insulin. It has been observed that a patient's insulin requirements may dramatically decrease during hospitalization. This study sought to systematically investigate this phenomenon.

METHODS: We performed a retrospective chart review of patients with U-500 insulin outpatient regimens who were admitted to the San Antonio Military Medical Center over a 5-year period. Each patient's outpatient total daily dose (TDD) of insulin was compared to the average inpatient TDD. The outpatient estimated average glucose (eAG) was calculated from the glycated hemoglobin (HbA1c) and compared to the average inpatient …

BACKGROUND: Several small studies found night-time awakenings due to COPD symptoms were associated with decreased health status. In this study, night-time awakenings in patients with COPD were examined and effects of tiotropium therapy evaluated.

METHODS: This study was a post hoc, exploratory, pooled analysis of twin, multicenter, double-blind, randomized, placebo-controlled, parallel-group trials. Patients with stable moderate-to-severe COPD were randomized to tiotropium HandiHaler® (n = 550) or placebo (n = 371) and followed for 13 weeks. During a 2-week, pre-treatment baseline period and for 13 weeks on treatment, self-reported night-time awakenings due to COPD symptoms, rescue medication (albuterol) use, and morning …

OBJECTIVE: To examine whether lung endothelial cells (ECs) from patients with systemic sclerosis (SSc)-associated interstitial lung disease (ILD) express mesenchymal cell-specific proteins and gene transcripts, indicative of the occurrence of endothelial-to-mesenchymal phenotypic transition (EndoMT).

METHODS: Lung tissue from 6 patients with SSc-associated pulmonary fibrosis was examined by histopathology and immunohistochemistry. Confocal laser microscopy was utilized to assess the simultaneous expression of EC and myofibroblast molecular markers. CD31+CD102+ ECs were isolated from the lung tissue of 2 patients with SSc-associated ILD and 2 normal control subjects, and the expression of EC and mesenchymal cell markers and other relevant genes was analyzed …

BACKGROUND: In phase 2 trials, treatment with the combination of the nucleotide polymerase inhibitor sofosbuvir and the NS5A inhibitor velpatasvir resulted in high rates of sustained virologic response in patients chronically infected with hepatitis C virus (HCV) genotype 2 or 3.

METHODS: We conducted two randomized, phase 3, open-label studies involving patients who had received previous treatment for HCV genotype 2 or 3 and those who had not received such treatment, including patients with compensated cirrhosis. In one trial, patients with HCV genotype 2 were randomly assigned in a 1:1 ratio to receive sofosbuvir-velpatasvir, in a once-daily, fixed-dose combination tablet …

BACKGROUND: Nitrates are commonly prescribed to enhance activity tolerance in patients with heart failure and a preserved ejection fraction. We compared the effect of isosorbide mononitrate or placebo on daily activity in such patients.

METHODS: In this multicenter, double-blind, crossover study, 110 patients with heart failure and a preserved ejection fraction were randomly assigned to a 6-week dose-escalation regimen of isosorbide mononitrate (from 30 mg to 60 mg to 120 mg once daily) or placebo, with subsequent crossover to the other group for 6 weeks. The primary end point was the daily activity level, quantified as the average daily accelerometer …

Neurology Articles

Vagus nerve stimulation (VNS) is a widely used adjunctive treatment option for intractable epilepsy. Most studies have demonstrated short-term seizure outcomes, usually for up to 5 years, and thus far, none have reported psychosocial outcomes in adults. We aimed to assess long-term seizure and psychosocial outcomes in patients with intractable epilepsy on VNS therapy for more than 15 years. We identified patients who had VNS implantation for treatment of intractable epilepsy from 1997 to 2013 at our Comprehensive Epilepsy Program and gathered demographics including age at epilepsy onset and VNS implantation, epilepsy type, number of antiepilepsy drugs (AEDs) and seizure …
