BACKGROUND: The cortical screw (CS) trajectory for pedicle screw placement is believed to require a smaller incision and less tissue dissection resulting in lower blood loss and faster healing; however, this has not yet been confirmed in clinical studies. OBJECTIVE: To compare CS transforaminal lumbar interbody fusions (TLIF), traditional pedicle screw (TPS) trajectory TLIFs, and posterolateral fusion (PLF) without interbody for differences in operative characteristics and complications...

Modern surgical departments are characterized by a high degree of automation supporting complex procedures. It recently became apparent that integrated operating rooms can improve the quality of care, simplify clinical workflows, and mitigate equipment-related incidents and human errors. Particularly using computer assistance based on data from integrated surgical devices is a promising opportunity. However, the lack of manufacturer-independent interoperability often prevents the deployment of collaborative assistive systems...

In this study freely suspended and Ca-alginate immobilized C. vulgaris cells were used for the biosorption of Fe(II), Mn(II), and Zn(II) ions, from the aqueous solution. Experimental data showed that biosorption capacity of algal cells was strongly dependent on the operational condition such as pH, initial metal ions concentration, dosages, contact time and temperature. The maximum biosorption of Fe(II) 43.43, Mn(II) 40.98 and Zn(II) 37.43 mg/g was achieved with Ca-alginate immobilized algal cells at optimum pH of 6...

Electrocardiogram (ECG) as one of the best methods to measure irregular heartbeats is a dispensable method for doctor to diagnose Acute Myocardial Infarction (AMI) patients. Most medical centers in Taiwan implement the reduction of Door to Balloon (D2B) time, which is defined as the time interval starting when an Acute-Myocardial-Infarction patient arrives at the Emergency Department, and ending when a catheter guide wire crosses the culprit lesion as the acute-myocardial-infarction treatment on the patient in the cardiac catheterization room...

Recent theoretical studies indicated that the Curie temperature of perovskite manganite thin films can be increased by more than an order of magnitude by applying appropriate interfacial strain to control orbital ordering. In this work, we demonstrate that the regular intercalation of BaTiO3 layers between La0.67Sr0.33MnO3 layers effectively enhances ferromagnetic order and increases the Curie temperature of La0.67Sr0.33MnO3/BaTiO3 superlattices. The preferential orbital occupancy of eg(x 2 -y 2 ) in La0.67Sr0...

Novel endovascular techniques hope to offer patients aortic arch repair with reduced morbidity compared to conventional arch surgery; however, current endovascular strategies remain challenged by the proximal seal zone, higher stroke rates, long-term durability and select anatomy. Hybrid arch repair offers patients a less invasive alternative that can treat more distal aorta than conventional arch repair yet still be performed via standard sternotomy. Areas Covered: This review will discuss the current evidence and future development of hybrid aortic arch and frozen elephant trunk reconstruction...

PURPOSE OF REVIEW: Given the extremely expensive nature of critical care medicine, it seems logical that intensivists should play an active role in designing efficient systems of care. The true value of intensivists, however, is not well defined. RECENT FINDINGS: Anesthesiologists have taken key roles in improving patient safety in the operating room. Anesthesia-related mortality rates have decreased from 20 deaths per 100 000 anesthetics in the early 1980s to less than one death per 100 000 currently...

BACKGROUND: Papaverine remains a popular agent to treat intraoperative microsurgical vasospasm. However, the recent shortage has forced surgeons to trial antispasmodic agents unproven in microsurgery, but commonly used in other areas. During this shortage we have trialed topical nitroglycerin to break intraoperative vasospasm. This study aims to analyze the outcomes of this medication on flap complications compared with papaverine. METHODS: All consecutive free flaps performed for breast reconstruction at a single institution were reviewed...

BACKGROUND: Various techniques have been employed for the early detection of perioperative cerebral ischaemia and hypoxia. Cerebral near-infrared spectroscopy (NIRS) is increasingly used in this clinical scenario to monitor brain oxygenation. However, it is unknown whether perioperative cerebral NIRS monitoring and the subsequent treatment strategies are of benefit to patients. OBJECTIVES: To assess the effects of perioperative cerebral NIRS monitoring and corresponding treatment strategies in adults and children, compared with blinded or no cerebral oxygenation monitoring, or cerebral oxygenation monitoring based on non-NIRS technologies, on the detection of cerebral oxygen desaturation events (CDEs), neurological outcomes, non-neurological outcomes and socioeconomic impact (including cost of hospitalization and length of hospital stay)...

BACKGROUND: The use of motion tracking has been proved to provide an objective assessment in surgical skills training. Current systems, however, require the use of additional equipment or specialised laparoscopic instruments and cameras to extract the data. The aim of this study was to determine the possibility of using a software-based solution to extract the data. METHODS: 6 expert and 23 novice participants performed a basic laparoscopic cholecystectomy procedure in the operating room...

Organic thin-film transistors (OTFTs) can be fabricated at moderate temperatures and through cost-effective solution-based processes on a wide range of low-cost flexible and deformable substrates. Although the charge mobility of state-of-the-art OTFTs is superior to that of amorphous silicon and approaches that of amorphous oxide thin-film transistors (TFTs), their operational stability generally remains inferior and a point of concern for their commercial deployment. We report on an exhaustive characterization of OTFTs with an ultrathin bilayer gate dielectric comprising the amorphous fluoropolymer CYTOP and an Al2O3:HfO2 nanolaminate...
