BACKGROUND: Since their introduction in 1993, anatomical implants have provided a more natural appearance in breast augmentation, and many surgeons advocate their use and promote the good aesthetic results. However, the risk of implant rotation makes some of them reluctant to use these devices. The rotation rate varies among authors. METHODS: The authors present a 6.5-year series of 531 patients who underwent primary breast augmentation with macrotextured anatomical implants in a Swedish facility performed by one consultant surgeon (P...

BACKGROUND: Radial pressure pulse wave (RPPW) examination has been a key diagnostic component of traditional Chinese medicine. The objective of this study was to investigate the changes in RPPW along with various hemodynamic variables after acupuncture stimulation and to examine the validity of pulse diagnosis as a modern diagnostic tool. METHODS: We conducted acupuncture stimulation at both ST36 acupuncture points in 25 healthy volunteers. We simultaneously assessed the RPPW by pulse tonometry; heart rate variability (HRV) by electrocardiogram; photoplethysmogram (PPG) signals, respiration rate, peripheral blood flow velocity and arterial depth by ultrasonography; and cardiac output by impedance cardiography, before, during and after a session of acupuncture stimulation...

Nivolumab, a new immune checkpoint inhibitor, binds to programmed cell death-protein 1 receptors on T cell, blockades binding of its ligands, and augments the immunologic reaction against tumor cells. Augmented immune response, however, may lead to immune-related adverse events. Herein we describe a rare case of bilateral anterior uveitis induced by nivolumab treatment for metastatic melanoma. A 54-year-old woman presented with mild conjunctival redness and blurred vision two months after initiating nivolumab treatment...

Takuro Washio, Hiroyuki Sasaki, Shigehiko Ogoh
Previous studies have suggested that the risk of ischemic stroke increases immediately after drinking coffee. Indeed, drinking coffee, that is, caffeine, acutely increases arterial stiffness as well as blood pressure and peripheral vascular resistance. On the other hand, it has been reported that arterial stiffening is associated with elevation in the pulsatility index (PI) of cerebral blood flow (CBF), which increases the risk of brain disease. However, the effect of drinking coffee on the PI of the CBF and its interaction with arterial stiffness remain unknown...

BACKGROUND: Oxytocin is a potent uterotonic agent that is widely used for induction and augmentation of labor. Oxytocin has a narrow therapeutic index and the optimal dosing for any individual woman varies widely. OBJECTIVE: The objective of this study was to determine if genetic variation in the oxytocin receptor (OXTR) or in the gene encoding G protein-coupled receptor kinase 6 (GRK6), which regulates desensitization of the OXTR, could explain variation in oxytocin dosing and labor outcomes among women being induced near term...

OBJECTIVES: Central (aorta) and Sano (right ventricle)-to-pulmonary artery (PA) shunts, palliative operations for infants with complex heart defects, can develop life-threatening thrombosis. We employed computational fluid dynamics (CFD) to study pulsatile flow in these shunts, with the goal to identify haemodynamic characteristics conducive to thrombus formation. METHODS: CFD, using the finite volume method with cardiac catheterization data, and computer simulations, based on angiography, were employed to determine flow-velocity field, wall shear stress (WSS) profile and oscillatory shear index (OSI)...

Individuals with type 1 diabetes (T1D) characteristically have high glycemic levels that over time can result in reactive fibrosis and abnormalities in myocardial function. T1 mapping with magnetic resonance imaging (MRI) can estimate the extent of reactive fibrosis by measurement of the extracellular volume fraction (ECV). The extent of alterations in the ECV and associated changes in left ventricular (LV) function and morphology in individuals with T1D is unknown. Fourteen individuals with long-term T1D and fourteen sex-, age-, and body mass index-matched controls without diabetes underwent MRI measurement of myocardial T1 and ECV values as well as LV function and morphology...

BACKGROUND: Increased augmentation index (AIx) is accompanied by an elevated cardiovascular risk. A reduction of AIx is known for long-term continuous positive airway pressure (CPAP) therapy. We hypothesised that acute preload and left ventricular workload effects AIx and subendocardial viability ratio (SEVR) as a marker of coronary flow reserve. METHODS: Increased augmentation index and central blood pressure parameters were measured by radial artery tonometry in 17 healthy men (32/±6years) at rest and during CPAP ventilation at pressures of 5, 10mbar and after recovery...

The effects of left ventricular (LV) cavity size on cardiac function and overload have not yet been fully elucidated. We performed a covariance structure analysis and drew theoretical path models to clarify the effects of hemodynamic parameters on the stroke volume index (SVI) as a marker of cardiac function and on the plasma B-type natriuretic peptide (BNP) level as a marker of cardiac overload. We simultaneously measured various hemodynamic parameters and the BNP levels during cardiac catheterization in 1,715 inpatients of our institution...

BACKGROUND: The augmentation index (AI) obtained from applanation tonometry of the radial artery is technically the easiest and quickest of available methods for assessing arterial stiffness. We tested the hypothesis that the radial AI is associated with the extent of coronary artery calcium (CAC) as assessed by coronary computed tomography (CCT). METHODS AND RESULTS: This study included 161 patients with known or suspected coronary artery disease undergoing central hemodynamic measurements and CCT...

BACKGROUND: There is growing concern about the use of opioids prior to total knee arthroplasty (TKA), and research has suggested that preoperative opioid use may lead to worse pain outcomes following surgery. We evaluated the pain relief achieved by TKA in patients who had and those who had not used opioids use before the procedure. METHODS: We augmented data from a prospective cohort study of TKA outcomes with opioid-use data abstracted from medical records. We collected patient-reported outcomes and demographic data before and 6 months after TKA...

OBJECTIVES: In mothers with pre-gestational or gestational diabetes, abnormal arterial stiffness (stiffer arteries) has been reported. The impact of abnormal maternal arterial stiffness on fetal placental and cardiovascular physiology is unknown. The purpose of the study was to determine the impact of maternal diabetes on maternal arterial stiffness and the association with fetal cardiovascular physiology as measured by fetal echocardiography. METHODS: Between December 2013 and January 2017 we conducted a prospective study on diabetic (otherwise healthy) and non-diabetic, healthy pregnant mothers (at 20-28 gestational weeks and 18-40 years of age) who had a normal fetal cardiac echocardiogram and obstetric ultrasound...

BACKGROUND: women´s experience of emergency caesarean section is often described as less positive compared to a vaginal birth or a planned caesarean section. Midwifery care for women where deviations from a normal birth process are present is a challenge. The aim of study was to compare self-reported birth outcomes for women undergoing birth through spontaneous onset of labour between those who actually had a vaginal birth and those who eventually had an emergency caesarean section. DESIGN AND SETTING: the study was part of a prospective longitudinal cohort study of parents' experiences, attitudes, and beliefs related to childbirth...

Prognostic biomarkers are useful in allogeneic stem cell transplantation (SCT) to predict survival and relapse outcomes. We sought to derive a prognostic scoring system, which augmented the predictive power of the disease risk index (DRI) by incorporating biomarkers and validating their significance after SCT. The outcomes of overall survival (OS) and relapse were assessed with non-relapse mortality (NRM) treated as a competing risk to relapse. Six hundred and two patients were identified through a retrospective analysis of allogeneic SCT recipients for haematological malignancy between 2000 and 2013 in a single centre...

The current report examined the longitudinal relations between cognitive self-regulation, physiological self-regulation, and externalizing problems. At age 4 (n = 98; 49 girls) and 6 (n = 87; 42 girls), children completed the Day-Night task, which taps the inhibitory control dimension of executive function. During the task, cardiac activity was measured and respiratory sinus arrhythmia (RSA) was derived as an index of parasympathetic activity. Mothers reported on externalizing problems. A cross-lagged path model was used to estimate longitudinal predictions while controlling for stability in all constructs over time...
