t-wave oversensing occurs when the counter starts giving dual beeps for every cardiac cycle instead of one. this usually happens when the monitoring lead displays a tall t wave, which is also sharp. r wave sensing algorithms of the devices do not sense t wave because the slow rate of the t wave is much less than that of the r wave. but the slow rate of t waves may change with time and also beca...

out showing any correlation between pre-CRT s-CEA level and pathologic tumor response [5]. Presently, few biomarkers are considered promising as CRT-predictive markers. The s-CEA level of preor post-CRT appears to be closely associated with the prognosis in LARC patients, but its predictive value for pathologic response needs to be further verified. Additionally, efficient individualized regime...

BACKGROUND Various types of preoperative chemoradiotherapy (CRT) have been established for rectal cancer; thus, Physicians will need to refine the selection of appropriate preoperative CRT for different patients since there are various treatment regimens. Oral tegafur-uracil (UFT) plus leucovorin (LV) is commonly used to treat rectal cancer in Japan. Oral chemotherapy offers patients many poten...

Cardiac resynchronization therapy (CRT), the application of biventricular stimulation to correct discoordinate contraction, is the only heart failure treatment that enhances acute and chronic systolic function, increases cardiac work, and reduces mortality. Resting myocyte function also increases after CRT despite only modest improvement in calcium transients, suggesting that CRT may enhance my...

Catheter-related thrombosis (CRT) is a serious complication in hematological patients, but the risk factors for its occurrence are not well established. The study objectives were to estimate the incidence of CRT and to identify the risk factors for developing CRT in hematological patients. In a prospective setting, 104 consecutive patients with 200 insertions of central venous catheters were en...

BACKGROUND Calreticulin (CRT) resides in the endoplasmic reticulum (ER) and functions to chaperone proteins, ensuring proper folding, and intracellular Ca(2+) homeostasis. Emerging evidence shows that CRT is a multifunctional protein with significant roles in physiological and pathological processes with presence both inside and outside of the ER, including the cell surface and extracellular sp...

PURPOSE Rectal cancer patients achieving pCR are known to have an excellent prognosis, yet no widely accepted consensus on risk stratification and post-operative management (e.g., adjuvant therapy) has been established. This study aimed to identify magnetic resonance imaging (MRI) high-risk factors for tumor relapse in pathological complete remission (pCR) achieved by rectal cancer patients who...

AIMS Patients with heart failure (HF) as well as atrial fibrillation (AF) have suboptimal response to cardiac resynchronization therapy (CRT). Identification of mechanical abnormalities, amenable to correction with CRT, might improve the selection of candidates and CRT efficiency. We evaluated whether abnormal septal motion, assessed by the presence of septal flash (SF) is related to CRT respon...

Cardiac resynchronization therapy (CRT) for the treatment of heart failure (HF) raises complex problems for informed consent. CRT with and without defibrillator backup has been demonstrated in clinical trials to improve symptoms from HF and decrease mortality.1–4 A CRT pacemaker (CRT-P) may improve symptoms and reduce mortality in selected patients, even without offering the specific protection...

Calreticulin (CRT) is a chaperone protein which normally resides in the endoplasmic reticulum (ER). However, recent studies have demonstrated that preapoptotic cancer cells release internalized CRT to their surface prior to death, and this surface exposure of CRT acts as an ‘eat-me’ signal to local phagocytes. Some chemotherapeutic agents and gamma-irradiation have been shown to induce ER stres...
