Background and hypothesis Intravenous thrombolysis with alteplase remains standard care prior to thrombectomy for eligible patients within 4.5 h of ischemic stroke onset. However, alteplase only succeeds in reperfusing large vessel arterial occlusion prior to thrombectomy in a minority of patients. We hypothesized that tenecteplase is non-inferior to alteplase in achieving reperfusion at initial angiogram, when administered within 4.5 h of ischemic stroke onset, in patients planned to undergo endovascular therapy...

The optimal duration and treatment strategies involving adjuvant endocrine therapy in early breast cancer remained largely undetermined. As data emerge on the various modalities of treatment in both pre- and postmenopausal groups, debates, and discussions continue. Most studies to date focused on the 5-year duration of treatment consisting of mainly tamoxifen. The Arimidex, Tamoxifen, Alone or in Combination (ATAC) study demonstrated that anastrozole is superior to tamoxifen and has become the mainstream treatment in postmenopausal women with early breast cancer, although the duration was arbitrarily set for 5 years, analogous to tamoxifen treatment...

BACKGROUND: Body composition is an important predictor of drug toxicity and outcome. Ipilimumab (Ipi), a monoclonal antibody used to treat metastatic melanoma, has specific toxicities. No validated biomarkers that predict Ipi toxicity and efficacy exist. Also, the impact of Ipi on body composition has not been established. METHODS: Patients with metastatic melanoma treated with Ipi between 2009 and 2015 were included. Body composition was assessed by computed tomography at baseline and after four cycles of Ipi...

BACKGROUND: Focused exploration (FE) and bilateral parathyroid exploration (BE) are the standard surgical options for patients with primary hyperparathyroidism. However, the relative risk of recurrence, persistence, overall failure, reoperation, and any complications associated with either surgical approach is unclear. This study compared the outcomes and complication rates after FE and BE for patients with primary hyperparathyroidism. METHODS: PubMed and Embase were searched for studies comparing these outcomes between FE and BE...

BACKGROUND: Psychologists have previously demonstrated that information recall is context dependent. However, how this influences the way we deliver medical education is unclear. This study aimed to determine if changing the recall context from the learning context affects the ability of medical students to recall information. METHODS: Using a free recall experimental model, fourteen medical student participants were administered audio lists of 30 words in two separate learning environments, a tutorial room and an operating theatre...

We describe here a strain of Yersinia pestis, G1670A, which exhibits a baseline mutation rate elevated 250-fold over wild-type Y. pestis. The responsible mutation, a C to T substitution in the mutS gene, results in the transition of a highly conserved leucine at position 689 to arginine (mutS(L689R)). When the MutSL 689R protein of G1670A was expressed in a ΔmutS derivative of Y. pestis strain EV76, mutation rates observed were equivalent to those observed in G1670A, consistent with a causal association between the mutS mutation and the mutator phenotype...

Endotoxin tolerance is a phenomenon where cells show reduced responsiveness toward repeated endotoxin stimulation. Regulation of tolerance occurs at multiple levels of the cell signaling cascade, and many of these levels are potentially regulated by miRNA, which are a class of small RNA that bind to mRNA to down-regulate gene expression at the post-transcriptional level. Roles have been identified for miR-146a, miR-221, miR-579, miR-125b, miR-155, let-7e, and miR-98 in regulating the TLR4 signaling pathway during the development of endotoxin tolerance at receptor, signaling pathway, and gene transcription and translational levels...

OBJECTIVE: While cardiopulmonary resuscitation (CPR) chest compression fraction (CCF) is associated with out-of-hospital cardiac arrest (OHCA) outcomes, there is no standard method for the determination of CCF. We compared nine methods for calculating CCF. METHODS: We studied consecutive adult OHCA patients treated by Alabama Emergency Medical Services (EMS) agencies of the Resuscitation Outcomes Consortium (ROC) during January 1, 2010 to October 28, 2010. Paramedics used portable cardiac monitors with real-time chest compression detection technology (LifePak 12, Physio-Control, Redmond, WA)...

BACKGROUND: Temporal artery biopsy (TAB) is performed during the diagnostic workup for giant cell arteritis (GCA), a vasculitis with the potential to cause irreversible blindness or stroke. However, treatment is often started on clinical grounds, and TAB result frequently does not influence patient management. The aim of this study was to assess the need for TAB in cases of suspected GCA. METHODS: We performed a retrospective review of 185 TABs performed in our institution from 1990 to 2010...

BACKGROUND: Apposition of wound edges by sutures provides a temporary scaffold and tension support for healing. We have developed a novel tissue-sealing technology, photoactivated tissue bonding (PTB), which immediately crosslinks proteins between tissue planes, thereby sealing on a molecular scale. OBJECTIVES: To determine the effectiveness of PTB for superficial closure of skin excisions and to compare the results with standard epidermal suturing. METHODS: A split-lesion, paired comparison study of 31 skin excisions was performed...

BACKGROUND: The status of resected lymph nodes in colon cancer determines prognosis and further treatment. The American Joint Committee on Cancer staging system has designated extramural nodules as nonnodal disease and classified them as extensions of the T category in the sixth edition and as site-specific tumor deposits in the seventh edition. Extracapsular lymph node extension is an established poor prognostic indicator in many cancers. Its significance in colon cancer has not been extensively investigated...

BACKGROUND: Cardiopulmonary bypass results in ischemia/reperfusion (I/R)-induced endotoxemia. We conducted a prospective randomized trial to investigate the effect of taurolidine, an antiendotoxin agent with antioxidant and membrane-stabilizing properties, on patients undergoing coronary artery bypass grafting (CABG). METHODS: A total of 60 patients undergoing CABG were randomized into 4 groups. St Thomas' Hospital cold crystalloid cardioplegia was used in groups A and B, and cold blood cardioplegia in groups C and D...

Motor unit number estimation (MUNE) allows for quantitative assessment of functional motor units in a nerve. Several techniques have been applied to human studies. Although MUNE has been performed in animals to study neurological disorders, reproducibility has not been addressed. We analyzed the test-retest reproducibility of an incremental MUNE technique in rabbits and performed histological correlation. A peroneal MUNE was performed in 9 rabbits on two occasions separated by 30 days. MUNE was then performed on 18 rabbits prior to euthanize...

BACKGROUND AND OBJECTIVE: We have developed a light-activated method called photochemical tissue bonding (PTB) for closing wounds using green light and a photosensitizing dye (Rose Bengal-RB) to initiate photochemical crosslinking of wound surface proteins. These studies were designed to determine whether RB causes phototoxicity during closure of skin incisions with PTB. STUDY DESIGN/MATERIALS AND METHODS: RB phototoxicity was evaluated after sealing incisions in porcine skin ex vivo and rabbit skin in vivo using PTB (1 mM RB, 100 J/cm(2), 532 nm, 0...
