REVIEW
Grace E Brown, Salman R Khetani
Drug-induced liver- and cardiotoxicity remain among the leading causes of preclinical and clinical drug attrition, marketplace drug withdrawals and black-box warnings on marketed drugs. Unfortunately, animal testing has proven to be insufficient for accurately predicting drug-induced liver- and cardiotoxicity across many drug classes, likely due to significant differences in tissue functions across species. Thus, the field of in vitro human tissue engineering has gained increasing importance over the last 10 years...

BACKGROUND: Many patients with tetralogy of Fallot (TOF) who underwent surgical correction of their congenital cardiac malformation during infancy develop right ventricular dysfunction and exercise intolerance in the long term. The right ventricle (RV) dilates due to the development of severe pulmonary regurgitation (and secondary tricuspid insufficiency). To reduce RV dilation and improve exercise tolerance pulmonary valve replacement (PVR) is the common therapeutic strategy. Whether concomitant tricuspid valve repair (TVR) is beneficial in these pure volume-overload conditions is still unknown...

Angiotensin-converting enzyme (ACE-I) inhibitors and ARBs have shown real efficacy in reducing blood pressure, proteinuria, in slowing the progression of chronic kidney disease (MRC) and in clinical improvement. in patients with heart failure, diabetes mellitus and ischemic heart disease. However, their use is limited by some side effects such as the increase in serum potassium (K), which can be particularly severe in patients with renal insufficiency. In the 23,000 patients followed by the PIRP project of the Emilia-Romagna Region, hyperkalaemia at the first visit (K> 5...

BACKGROUND: Literature data on hepcidin (H) level - the main regulator of systemic iron homeostasis in patients with chronic heart failure (CHF) - are contradictory. Relationships of H with markers of inflammation elevated level of which is characteristic of CHF are insufficiently studied. The latter problem remains practically unexplored in elderly and very old patients with CHF. AIM: to study the role of H in formation of anemia of chronic disease (ACD) and iron deficiency anemia (IDA) in elderly and very old patients with CHF...

In many patients, chronic heart failure (CHF) is associated with chronic kidney disease (CKD). Virtually all patients with terminal CKD and many patients with early CKD display various disorders of mineral and bone metabolism (MBM) related with all-cause mortality and high risk of cardiovascular complications. This review addressed disorders of mineral and bone metabolism in patients with CHF, including hypocalcemia, hyperphosphatemia, vitamin D insufficiency/deficiency, secondary hyperparathyroidism, changed levels of FGF23 and Klotho, osteoporosis, osteopenia, their clinical and prognostic significance, and possibilities of their correction...

Background: Patients with a diagnosis of coronary artery disease (CAD) may face important decisions regarding treatment options, with the "right choice" depending on the relative weights of risks and benefits. Studies performed as discrete choice experiments are used to estimate these weights, and attribute selection is an essential step in the design of these studies. Attributes not included in the design cannot be analyzed. In this study, we aimed to elicit, rank, and rate attributes that may be considered important to patients and physicians who must choose between angioplasty and surgery for coronary revascularization...

Although cardiovascular responses may be altered by respiratory changes under prolonged hypoxia, the relationship between respiratory and cardiovascular changes remains unknown. The aim of the present study is to clarify cardiorespiratory changes in anesthetized rats during and after hypoxic conditions using simultaneous recordings of cardiorespiratory variables with 20-sec recording intervals. After air breathing for 20 min (pre-exposure period), rats were subjected to 10% O2 for 2 h (hypoxic exposure period) and then air for 30 min (recovery period)...

BACKGROUND: Pompe disease is a lysosomal storage disease with an autosomal recessive inheritance characterized by an insufficient activity of the acid alpha-glucosidase enzyme. The incidence varies from 1:40000 to 1:200000 live births and cardiac involvement in adults is rare. Chagas disease is an infection caused by the protozoan Trypanosoma cruzi, in which one-third of the cases progress to the chronic form, and may lead to cardiac involvement, usually from the fifth decade of life onwards...

BACKGROUND: The heart rate variability (HRV) derived Analgesia Nociception Index (ANI™ ) is a continuous non-invasive tool to assess the nociception/anti-nociception balance in unconscious patients. It has been shown to be superior to hemodynamic variables in detecting insufficient anti-nociception in children, while little is known about its predictive value. METHODS: The primary objective of this prospective observational pilot study in paediatric surgical patients under sevoflurane anaesthesia, was to compare the predictive value of the ANI and heart rate to help decide to give additional opioids...

The authors consecutively assessed various arterial pulse-wave velocity (PWV) indices and ankle-brachial index (ABI) by an automatic device (VP2000, OMRON Health Care Co. Ltd., Kyota, Japan) in outpatients with ≥ 1 cardiovascular risk. PAD was defined as ABI ≤ 0.9. Among 2309 outpatients (mean age 62.4 years), worse renal function was associated with higher brachial-ankle PWV, heart-carotid PWV, heart-femoral PWV (hf-PWV), and lower ABI (all P < .001). Multivariate regression models showed independent associations between lower eGFR, lower ABI (Coef: 0...
