AIMS: We recently reported the feasibility of the average pixel intensity (API) method for grading mitral regurgitation (MR) in a heterogeneous MR population. Since mitral valve prolapse (MVP) is an important cause of primary MR, we more specifically investigated the feasibility of the API method and the MR flow dynamics in patients with MVP. METHODS: Transthoracic echocardiography was performed by a single operator in consecutive MVP patients (n=112). MR was assessed using the API method, color Doppler, vena contracta width (VCW), effective regurgitant orifice area (PISA-EROA) and regurgitant volume (PISA-RV)...

A diastereodivergent approach to highly substituted bicyclo[3.1.0]hexanes has been developed through a transannular alkylation reaction that builds up the bicyclic core employing asymmetric organocatalysis as the tool for the installation of all stereocenters. On one hand, a Michael/Michael cascade process between enals and 4-alkenyl sulfamidate imines under the iminium/enamine activation manifold provides a oxathiazole-2,2-dioxide-fused cyclohexane adduct that, after isolation, is subsequently engaged in a transannular alkylation/hydrolysis through enamine activation by the use of a primary amine...

BACKGROUND: Unintentional extubation is a well-documented and potentially life-threatening phenomenon. There is little research into the factors that lead to unintentional extubation, and therefore how to prevent it. Endotracheal tubes (ETTs) are commonly secured with 1 cm twill tape, but there is little evidence on how to best tie them in place. We have devised a new knot for securing these tubes in place, and we have assessed its degree of slippage when exposed to both perpendicular and sliding forces in comparison with other commonly used knots...

Exposure of operators to ionising radiation in interventional cardiology has likely diminished, but data confirming the magnitude of the reduction are lacking. The aim of this study was to compare the dose of radiation received by interventional cardiology operators at 11 years interval (2006 vs 2017). The study population comprised all interventional coronary procedures performed by a single operator in one catheterization laboratory (cathlab) of a large university hospital in north-eastern France. Exposure was compared between two periods, namely period 1 (from October 2005 to March 2006) and period 2 (from March 2017 to June 2017)...

PURPOSE: The aim of the study was to evaluate the progression and rotation of the fetal head during the second stage of labor using translabial ultrasound and to compare ultrasonographic data obtained in nulliparous women both receiving and not receiving neuraxial analgesia. METHODS: The 49 patients enrolled in the study were divided into two groups according to receiving or not receiving neuraxial analgesia. Every half hour from full dilation to delivery, the ultrasonographic translabial parameters of Angle of Progression, Head Symphysis Distance, and Midline Angle were obtained and recorded by a single operator...

Elevated levels of total dissolved gas (TDG) may occur downstream of dams during the spill process. These high levels would increase the incidence of gas bubble disease in fish and cause severe environmental impacts. With increasing numbers of cascade hydropower stations being built or planned, the cumulative effects of TDG supersaturation are becoming increasingly prominent. The TDG saturation distribution in the downstream reaches of the Jinsha River was studied to investigate the cumulative effects of TDG supersaturation resulting from the cascade hydropower stations...

BACKGROUND: Lung ultrasound examination is becoming an even more important part of pulmonologists' clinical routine. As indicated in literature, the coordinates of any findings on lung parenchyma are based on surface landmarks or conventional quadrants. In our experience we noticed that lung fissures are clearly detectable as interruptions of the pleural line but this was never investigated before. The aim of the study is to evaluate if lung fissures are detectable in normal conditions in routine clinical practice...

PURPOSE: Primary aldosteronism (PA) is a common cause of secondary hypertension. Adrenal venous sampling (AVS) is the gold standard for assessing laterality of PA, which is of paramount importance to decide adequate treatment. AVS is a technically complicated procedure with success rates ranging between 30% and 96%. The aim of this study was to investigate the success rate of AVS over time, performed by a single interventionalist. METHODS: This was a retrospective study based on consecutive AVS procedures performed by a single operator between September 2005 and June 2016...

OBJECTIVE: Percutaneous closure of patent foramen ovale (PFO) and atrial septal defect (ASD) is routinely performed under general anesthesia or deep sedation and use of transesophageal (TEE) or intracardiac echocardiography, incurring longer duration and higher cost. We have used a simplified, economical, fluoroscopy-only guided approach with local anesthesia, and herein report our data. METHODS: The study includes 112 procedures in 110 patients with PFO (n=75) or ASD (n=35), with use of an Amplatzer occluder, heparin and prophylactic antibiotics...

Direct oesophagoscopy is largely a diagnostic procedure performed for a variety of symptoms (e.g. unilateral otalgia or odonophagia) or as part of a panendoscopy to exclude a synchronous primary; therefore good visualisation of abnormal mucosa is essential. The current standard oesophagoscopy technique involves direct visualisation from approximately 25cm down a narrow, illuminated oesophagoscope limiting visualisation of abnormal mucosa. Usually performed by a single operator, the technique is difficult to teach, as the trainee is unable to visualise what the trainer is seeing endoluminally and visa versa...

Background and study aims:  Endoscopic removal of biliary stones has high success rates, ranging between 85 % to 95 %. Nevertheless, some stones may be challenging and different endoscopic methods have evolved. Papillary large balloon dilation after sphincterotomy is a widely used technique with success rates ranging from 68 to 90 % for stones larger than 15 mm. Cholangioscopy allows performing lithotripsy under direct biliary visualization, either by laser or electrohydraulic waves, which have similar success rate (80 % - 90 %)...
