Poincare plots are commonly used to study the nonlinear behavior of physiologic signals. The aim of this study is to evaluate the Poincare plot indices of human heart rate signals during meditation. ⋯ The comparative dynamic measures of the Poincare plot indices during and before meditation give more insight of the heart rate signals in a specific psychophysiological state.

Herpes viruses can be reactivated among immunocompetent patients in intensive care unit (ICU). Cytomegalovirus (CMV) and herpes simplex virus (HSV) have been the most studied. We hypothesized that Epstein-Barr virus (EBV) could also be reactivated in immunocompetent patients during their stay in ICU and that this would be associated with morbidity and mortality. ⋯ This study shows that EBV DNA is detected in blood of diverse ICU patients with ≥ 5 days of stay and that it is associated with morbidity and mortality. Larger dynamic prospective studies are needed to correlate viral reactivation with immune system evolution during ICU stay and to determine the role of polyviral reactivations.

Three equations have been often used to estimate glomerular filtration rate (GFR), namely, Modification of Diet in Renal Disease (MDRD), MDRD for Chinese (MDRDc), and Cockcroft-Gault (CG), for the purpose of screening individuals with chronic kidney disease (CKD). However, neither of these equations has been tested in a large Asian population. The aim of this study was to determine which equations were suitable for screening CKD in a large Taiwanese population. ⋯ The use of the CG equation in the Taiwanese population is inappropriate for screening individuals with CKD, and the MDRDc equation seems to be better for Taiwanese population.

Thromboprophylaxis after minimally invasive total knee arthroplasty: a comparison of rivaroxaban and enoxaparin.
Total knee arthroplasty (TKA) carries a substantial rate of venous thromboembolism (VTE). The blood-saving of effect of tranexamic acid (TEA) in TKA using enoxaparin for thromboprophylaxis has been well known. However, the routine use of chemoprophylaxis in TKA remains controversial because of postoperative bleeding complications. Therefore, the purpose of this study was to retrospectively compare the incidence of VTE, and postoperative blood loss and wound-related complications in minimally invasive (MIS)-TKA patients who received rivaroxaban or enoxaparin prophylaxis. ⋯ Our retrospective study demonstrated a low rate of VTE in MIS-TKA patients who received rivaroxaban or enoxaparin when TEA was used for bleeding prophylaxis. No increased perioperative bleeding or postoperative wound-related complications were observed in the rivaroxaban group compared with the enoxaparin group.

Malnutrition has been associated with poor health outcomes in hospitalized patients. This study assessed the validity of the scored patient-generated subjective global assessment (PG-SGA) in adult patients who had undergone an open appendectomy, and examined the association of this assessment tool with length of hospital stay. ⋯ The scored PG-SGA in adults receiving an appendectomy is significantly associated with length of hospital stay, and is an effective tool for assessing the nutritional status of patients with cancer and chronic illness, as well as of patients with acute surgical abdomen.
