Factors associated with time-to-surgery (TTS) and survival in colon cancer has not been well studied. Cancer Care Ontario recommends surgery within 42 days of diagnosis and that 90% of patients meet this benchmark. We describe factors associated with TTS and survival in routine clinical practice. METHODS: Retrospective population-based cohort study of patients receiving elective colonic resection after diagnosis of colon cancer in Ontario, Canada from 2002 to 2008 followed until 2012...

AIMS: Early research has proposed that patients with Takotsubo syndrome (TTS) could have a higher mortality rate than the general population. Our study was conducted to determine the short- and long-term outcome of TTS patients associated with a significantly compromised left ventricular function on hospital admission. METHODS AND RESULTS: Our institutional database constituted a collective of 112 patients diagnosed with TTS between 2003 and 2015. The patients were classified into two groups based on the left ventricular ejection fraction (LVEF), with those presenting with a LVEF >35% on admission categorized into one group (n=65, 58%) and those presenting with LVEF ≤35% (n=47, 42%) categorized into another group...

Introduction: Traditional graded-exercise tests to volitional exhaustion (GXTs) are limited by the need to establish starting workloads, stage durations, and step increments. Short-duration time-trials (TTs) may be easier to implement and more ecologically valid in terms of real-world athletic events. The purpose of the current study was to assess the reliability and validity of maximal oxygen uptake ([Formula: see text]max) and performance measured during a traditional GXT (STEP) and a four-minute running time-trial (RunTT)...

Esophageal leaks (EL) and ruptures (ER) are rare conditions associated with a high risk of mortality and morbidity. Historically, EL and ER have been surgically treated, but current treatment options also include conservative management and endoscopy. Over the last decades, interventional endoscopy has evolved as an effective and less invasive alternative to primary surgery in these cases. A variety of techniques are currently available to re-establish the continuity of the digestive tract, prevent or treat infection related to the leak/rupture, prevent further contamination, drain potential collections, and provide nutritional support...

Transverse-axial tubules (TTs) are key structures involved in cardiac excitation-contraction coupling and can become deranged in disease. Although optical measurement of TTs is frequently employed to assess TT abundance and regularity, TT dimensions are generally below the diffraction limit of optical microscopy so determination of tubule size is problematic. TT diameter was measured by labeling both local surface membrane area and volume with fluorescent probes (FM4-64 and calcein, respectively), correcting image asymmetry by image processing and using the relationship between surface area and volume for a geometric primitive...

In the past few years, metastatic renal cell carcinoma prognosis was improved by the development of molecular targeted therapies (TTs). At the metastatic stage, the tolerance to treatment is a major concern, not only because of the challenge of the efficacy/toxicity ratio improvement but also because of the importance of an optimal adherence to oral treatments. The present case series relates the issues of dealing with uncommon and sometimes never described side effects of sunitinib and sorafenib. The first case report deals with grade 3 vomiting during hemodialysis with concurrent administration of sunitinib...

Brachytherapy is a type of radiotherapy wherein titanium capsules containing therapeutic radioisotopes are implanted within tumor tissues, enabling high-dose radio-irradiation to tumor tissues around the seeds. Although marked therapeutic effects have been demonstrated, brachytherapy needs complicated implantation technique under general anesthesia and the seeds could migrate to other organs. The aim of this study is to establish a novel brachytherapy using biocompatible, injectable thermo-responsive polymers (polyoxazoline; POZ) labeled with yttrium-90 ((90)Y), which can self-aggregate above a specific transition temperature, resulting in long-term intratumoral retention of radioactivity and therapeutic effect...

Thyroid hormones (THs) and their derivatives require transmembrane transporters (TTs) to mediate their translocation across the cell membrane. Among these TTs, the L-type amino acid transporters (LAT) not only transport amino acids (AAs) but also certain THs and their derivatives. This review summarizes available knowledge concerning structure function patterns of the TH transport by LAT1 and LAT2. For example, LAT2 imports 3,3'-T2 and T3, but not rT3 and T4. In contrast to amino acids, THs are not at all exported by LAT2...

It is postulated that hemodynamic changes occur in the distal vascular bed post-deployment of Pipeline Embolization Devices (PEDs). In this paper, we evaluate changes in the contrast transit times (TTs) on digital subtraction angiography (DSA) post-PED interventions. DSA films were analyzed using custom-made software for the time-density relationship at baseline and compared to post-PED deployment. All analyses were performed within the middle cerebral artery (MCA) M1 segment. Analyses included TT10%-100% (time needed for the contrast to change from 10% image intensity to 100%), TT100%-10%, and TT25%-25%...

Introduction: Afferent information from exercising muscle contributes to the sensation of exercise-induced muscle pain. Transcutaneous electrical nerve stimulation (TENS) delivers low-voltage electrical currents to the skin, inhibiting nociceptive afferent information. The use of TENS in reducing perceptions of exercise-induced pain has not yet been fully explored. This study aimed to investigate the effect of TENS on exercise-induced muscle pain, pacing strategy, and performance during a 5-km cycling time trial (TT)...
