OBJECTIVES: Stroke volume variation and pulse pressure variation do not reliably predict fluid responsiveness during low tidal volume ventilation. We hypothesized that with transient increase in tidal volume from 6 to 8 mL/kg predicted body weight, that is, "tidal volume challenge," the changes in pulse pressure variation and stroke volume variation will predict fluid responsiveness. DESIGN: Prospective, single-arm study. SETTING: Medical-surgical ICU in a university hospital...

PURPOSE OF REVIEW: This article uses a case-based approach to highlight the clinical features as well as recent advances in molecular genetics, muscle imaging, and pathophysiology of the congenital myopathies. RECENT FINDINGS: Congenital myopathies refer to a heterogeneous group of genetic neuromuscular disorders characterized by early-onset muscle weakness, hypotonia, and developmental delay. Congenital myopathies are further classified into core myopathies, centronuclear myopathies, nemaline myopathies, and congenital fiber-type disproportion based on the key pathologic features found in muscle biopsies...

The field of arrhythmia monitoring is changing rapidly. The rapid advent of technology in combination with marked improvements in cellular communication and an increased desire by patients to be actively engaged in their care has ushered in a new era of clinical care. Today, physicians need to think about their patients outside the traditional in-office setting. Two technologies that embody this changing landscape are smartphone-based electrocardiographic (ECG) monitors and remote monitoring of cardiac implantable electronic devices (CIEDs)...

Purpose Cardiac dysfunction is a serious adverse effect of certain cancer-directed therapies that can interfere with the efficacy of treatment, decrease quality of life, or impact the actual survival of the patient with cancer. The purpose of this effort was to develop recommendations for prevention and monitoring of cardiac dysfunction in survivors of adult-onset cancers. Methods Recommendations were developed by an expert panel with multidisciplinary representation using a systematic review (1996 to 2016) of meta-analyses, randomized clinical trials, observational studies, and clinical experience...

BACKGROUND: Hypothermia in neonatal intensive care unit patients is associated with morbidity. Perioperative normothermia is the standard of care. AIMS: We hypothesized that a quality improvement intervention (transport protocol, transport education, ongoing monitoring) would decrease the incidence of perioperative hypothermia. Secondarily, we hypothesized that patients undergoing surgery at a postmenstrual age of <37 weeks or at a weight of <1.5 kg would be at higher risk for perioperative hypothermia...

This article will consider how physiological monitoring can be used both as an intrinsic part of an experiment, or for removing unwanted physiological signals from the FMRI time series. As functional MRI is used for a wide variety of applications beyond the identification of regions involved in a task, different sources of noise in the time series become important. The use of arterial spin labelling sequences, either in isolation or combined with BOLD imaging, means that temporal noise must be dealt with differently...

OBJECTIVES: Kidney transplant is the gold standard for treatment of renal failure. With the increasing age of the recipient population, which carries significant comorbidities, and the use of more marginal organs, there is potential for increased critical care admissions. In this study, we investigated the incidence, indications, and outcomes of patients admitted to critical care within 1 year of transplant. We also aimed to identify any precipitating factors or events that may trigger these admissions, as well as establish variables that could affect mortality...

OBJECTIVES: There is ambiguity concerning the walk tests available for functional assessment of coronary patients, particularly for the walking speed. This study explores the psychometric properties of two walking tests, based on fixed-distance tests, at comfortable and fast velocity, in stabilized patients at the end of a cardiac rehabilitation program. METHODS: At a three-day interval 58 coronary patients (mean age of 64.85±6.03 years, 50 men) performed three walk tests, the first two at a comfortable speed in a random order (6-minute walk test - 6MWT - and 400-metre comfortable walk test - 400mCWT) and the third at a brisk speed (200-metre fast walk test - 200mFWT)...

INTRODUCTION: Shock, defined as a state of tissue hypoperfusion and the tissues reperfusion, is the main goal of management of shock. Increase in central venous saturation (CvSo2) and decrease in blood lactate level are useful in assessment of adequacy of tissue perfusion. Near-infrared spectroscopy is a noninvasive way to observe real-time changes in regional cerebral saturation and has been used in patients with different brain diseases. There is a small body of literature suggesting that cerebral regional oxygen saturation (CrSo2) monitoring added a value in assessment and management of intensive care unit (ICU) patients...

BACKGROUND: Postoperative new-onset atrial fibrillation (PNAF) is the most common complication following cardiac surgery. The inflammatory response, as a potential underlying mechanism, has been extensively studied. In small studies, the white blood cell count (WBC) has been shown to be the only consistent inflammatory marker associated with PNAF. This study aimed to determine the association between perioperative WBC response and PNAF in a larger study cohort. METHODS: Patients ≥18years, undergoing elective cardiac surgery with a preoperative sinus rhythm were included...

PURPOSE: Near-infrared spectroscopy sensors often cannot be attached at the commercially recommended locations because combined use of neurological monitoring systems is common during on-pump cardiac surgery. The primary purpose of this study was to compare the incidence of regional cerebral oxygen desaturation and regional cerebral oxygen saturation values detected using near-infrared spectroscopy between the upper and lower forehead during on-pump cardiac surgery. METHODS: A prospective observational study was conducted with 25 adult patients scheduled for elective on-pump cardiac surgery...

BACKGROUND: Critical care patients are at increased risk of infection. Near-patient surfaces act as reservoirs of microbial soil, which may contain pathogens. AIM: To correlate soil levels with hand-touch frequency of near-patient sites in an intensive care unit (ICU). METHODS: Five sites around each bed in a 10-bed ICU were screened for total microbial soil (cfu/cm(2)) and Staphylococcus aureus every month for 10 months. Selected sites were infusion pump and cardiac monitor, left and right bedrails, and bed table...

Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are expressed ubiquitously throughout the brain, where they function to regulate the excitability of neurons. The subcellular distribution of these channels in pyramidal neurons of hippocampal area CA1 is regulated by tetratricopeptide repeat-containing Rab8b interacting protein (TRIP8b), an auxiliary subunit. Genetic knockout of HCN pore forming subunits or TRIP8b, both lead to an increase in antidepressant-like behavior, suggesting that limiting the function of HCN channels may be useful as a treatment for Major Depressive Disorder (MDD)...

Doxorubicin (DOX) is a well-known cytotoxic agent used extensively as a chemotherapeutic drug to eradicate a wide variety of human cancers. Reactive oxygen species (ROS)-mediated oxidative stress during DOX treatment can induce cardiac, renal, and hepatic toxicities, which can constrain its use as a potential cytotoxic agent. The present work investigates the antioxidant potential of naringenin (NAR) against DOXinduced toxicities of a Dalton's lymphoma ascites (DLA) tumor-bearing mouse model. Mice were randomized into four groups: a negative control, positive control, DOX (2...
