BACKGROUND Central venous catheterization is a common tool used in critically ill patients to monitor central venous pressure and administer fluids and medications such as vasopressors. Here we present a case of a missing guide wire after placement of peripherally inserted central catheter (PICC), which was incidentally picked up by bedside ultrasound in the intensive care unit.  CASE REPORT A 50-year-old Hispanic male was admitted to the intensive care unit for alcohol intoxication. He was managed for septic shock and required placement of a peripherally inserted central line in his left upper extremity for antibiotics and vasopressor administration...

BACKGROUND: Establishing clinically accessible measures of cartilage health is critical for assessing effectiveness of protocols to reduce risk of osteoarthritis (OA) development and progression. Cartilage thickness is one important measure in describing both OA development and progression. The objective was to determine the relationship between ultrasound and MRI measures of cartilage thickness in the medial femoral condyle. METHODS: Mean cartilage thicknesses of the left medial femoral cartilage were measured via T1 weighted MRI and ultrasound imaging from transverse, anterior, middle, and posterior medial femoral regions in 10 healthy females (Mean±Std Dev) (1...

Many cardiovascular diseases can alter arterial stiffness; therefore, measurement of arterial wall stiffness can provide valuable information for both diagnosis of such diseases in the clinic and evaluation of the effectiveness of relevant drugs. However, quantitative assessment of the in vivo elastic properties of arterial walls in a non-invasive manner remains a great challenge. In this study, we found that the elastic modulus of the arterial wall can be extracted from the dispersion curve of the guided axial wave (GAW) measured using the ultrasound elastography method...

BACKGROUND: It is very important to assess the effectiveness of prone positioning (PP) in patients with severe acute respiratory distress syndrome (ARDS). However, it is difficult to identify patients who may benefit from PP. The purpose of this study was to investigate whether prone positioning potential (PPP) can be predicted by lung ultrasound in patients with ARDS. METHODS: In this prospective study, 45 patients with ARDS were included for the assessment of PPP...

BACKGROUND: Critically ill patients frequently suffer muscle weakness whilst in critical care. Ultrasound can reliably track loss of muscle size, but also quantifies the arrangement of the muscle fascicles, known as the muscle architecture. We sought to measure both pennation angle and fascicle length, as well as tracking changes in muscle thickness in a population of critically ill patients. METHODS: On days 1, 5 and 10 after admission to critical care, muscle thickness was measured in ventilated critically ill patients using bedside ultrasound...

Fluid balance management is of great importance in the critically ill cardiac patient. Although intravenous fluids are a cornerstone therapy in the management of unstable patients, excessive administration coupled with cardiac dysfunction leads to elevation in central venous pressure and end-organ venous congestion. Fluid overload is known to have a detrimental effect on organ function and is responsible for significant morbidity in critically ill patients. Multisystem bedside point of care ultrasound imaging can be used to assess signs of fluid overload and venous congestion in critically ill patients...

Lipid-coated microbubbles are used to enhance ultrasound imaging and drug delivery. Here we apply these microbubbles along with low intensity pulsed ultrasound (LIPUS) for the first time to enhance proliferation and chondrogenic differentiation of human mesenchymal stem cells (hMSCs) in a 3D printed poly-(ethylene glycol)-diacrylate (PEG-DA) hydrogel scaffold. The hMSC proliferation increased up to 40% after 5 days of culture in the presence of 0.5% (v/v) microbubbles and LIPUS in contrast to 18% with LIPUS alone...

Marine microalgae and seaweeds (microalgae) represent a sustainable source of various bioactive natural carotenoids, including β-carotene, lutein, astaxanthin, zeaxanthin, violaxanthin and fucoxanthin. Recently, the large-scale production of carotenoids from algal sources has gained significant interest with respect to commercial and industrial applications for health, nutrition, and cosmetic applications. Although conventional processing technologies, based on solvent extraction, offer a simple approach to isolating carotenoids, they suffer several, inherent limitations, including low efficiency (extraction yield), selectivity (purity), high solvent consumption, and long treatment times, which have led to advancements in the search for innovative extraction technologies...

Atherosclerotic Renal Artery Stenosis is a form or peripheral arterial disease that tends to affect older subjects with hyperlipidemia, history of tobacco use, and who have other coexistent forms of vascular insufficiency. An abdominal bruit on physical exam can be a helpful clue. Slowly progressive, it can lead to critical narrowing of the renal arteries which creates a cascade of events such as renin-angiotensin-aldosterone activation (RAAS), hypertension, acute pulmonary edema, and renal fibrosis. The hypertension is considered a secondary form and can even be resistant to multiple antihypertensives...

Central vein cannulation is one of the most commonly performed procedures in intensive care. Traditionally, the jugular and subclavian vein are recommended as the first choice option. Nevertheless, these attempts are not always obtainable for critically ill patients. For this reason, the axillary vein seems to be a rational alternative approach. In this narrative review, we evaluate the usefulness of the infraclavicular access to the axillary vein. The existing evidence suggests that infraclavicular approach to the axillary vein is a reliable method of central vein catheterization, especially when performed with ultrasound guidance...

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) is the preferred treatment of choice for renal calculi. PCNL has evolved remarkably since the eighties when it was first described. APPROACH: Approach might be by either supine or prone and the access is made with the help of either fluoroscopy or ultrasound. Recently endoscopy guided puncture has also been described. MINIATURIZATION: Traditionally the tract size for PCNL used to be 30Fr. Even though the stone clearance rate was good there were complications such as bleeding With the advent of excellent optics and advances in stone fragmentation the tract size has reduced to a great extent which has reduced the complications without compromising the stone clearance...

Despite significant advances in the treatment of systemic cancers, progress in the treatment of primary brain tumors has been quite modest. In addition, an increasing proportion of patients with systemic cancers are presenting with brain-only metastases. These observations highlight the critical role that the blood-brain barrier plays in preventing antineoplastic therapies from reaching the central nervous system in therapeutic concentrations. This review describes the anatomy of the blood-brain barrier and currently available methods to quantify the entry of therapeutic compounds into the brain...

Focused ultrasound with microbubbles has been used to noninvasively and selectively deliver pharmacological agents across the blood-brain barrier (BBB) for treating brain diseases. Acoustic cavitation monitoring could serve as an on-line tool to assess and control the treatment. While it demonstrated a strong correlation in small animals, its translation to primates remains in question due to the anatomically different and highly heterogeneous brain structures with gray and white matteras well as dense vasculature...
