Looking in a mirror, laparoscopic gastric sleeve in situs inversus patient: a case report.

Laparoscopic sleeve gastrectomy has been widely accepted and adopted as a weight loss procedure for obesity. Although technically demanding, it is feasible and can improve patients' overall health. However, any variation from normal anatomy can be challenging for any surgery, especially bariatric surgery, where a mistake could mean going from a life-saving opportunity to costing the patient's life.

Data on accumulative allocation of water rights in the Atacama Desert (Antofagasta Region, northern Chile), 1905-2018.

This article presents a dataset on the accumulated water flow (L/s) granted in the Antofagasta Region for each year between 1905 and 2018. We produced the dataset starting from the official public records on water rights ( RPDAA), which are free to access and available at the National Water Agency's website (, DGA). The initial data described 1047 individual water rights granted in the Antofagasta Region according to 65 criteria.

New classification of directly compressible (DC) excipients in function of the SeDeM Diagarm Expert System.

As a methodology for characterizing substances with regard to its viability in direct compression, the SeDeM Diagram Expert System may be considered a new tool in terms of the number of parameters applied and its optimization. The paper is based on the experimental SeDeM characterization study of 51 directly compressible (DC) excipients. After selecting the parameters, and comparing the corresponding results, the choices available within the SeDeM Expert System could be expanded.

Optimization of parameters of the SeDeM Diagram Expert System: Hausner index (IH) and relative humidity (%RH).

As a methodology for characterizing substances in relation to their viability in direct compression, the SeDeM Diagram Expert System may be considered an open system in terms of the number of parameters applied and the optimization of these parameters. With the experience acquired from applying the SeDeM Diagram, in this study, we propose optimizing the parameters corresponding to the Hausner index (IH) and relative humidity (%HR) in order to simplify the mathematical calculation, so that it provides reliable data that can be extrapolated. The proposed optimization does not involve a conceptual change in the parameters considered nor a significant change in the results obtained compared with the previous calculation methodology initially established for the SeDeM Diagram Expert System, which means that the conclusions obtained by applying this method are equivalent.

Application of the SeDeM Diagram and a new mathematical equation in the design of direct compression tablet formulation.

Application of the new SeDeM Method is proposed for the study of the galenic properties of excipients in terms of the applicability of direct-compression technology. Through experimental studies of the parameters of the SeDeM Method and their subsequent mathematical treatment and graphical expression (SeDeM Diagram), six different DC diluents were analysed to determine whether they were suitable for direct compression (DC). Based on the properties of these diluents, a mathematical equation was established to identify the best DC diluent and the optimum amount to be used when defining a suitable formula for direct compression, depending on the SeDeM properties of the active pharmaceutical ingredient (API) to be used.

Left ventricular mass index as a prognostic factor in patients with severe aortic stenosis and ventricular dysfunction.

Ventricular dysfunction and high hypertrophy may influence surgical outcome in aortic stenosis. Our aim was to determine whether an excessive left ventricular mass index (LVMI) discriminates different risk profiles in aortic stenosis with low ventricular ejection fraction (LVEF). Three hundred and thirty-nine patients with severe aortic stenosis underwent valve replacement (Mar-1994 and Nov-2001).

A new expert systems (SeDeM diagram) for control batch powder formulation and preformulation drug products.

The new SeDeM Method is proposed for testing the batch-to-batch reproducibility of the same active pharmaceutical ingredient (API) in powder form. The procedure describes the study of the galenic properties of substances in powder form in terms of the applicability of direct compression technology. Through experimental determination of the SeDeM Method parameters, and their subsequent mathematical treatment and graphical expression (SeDeM Diagram), three batches of the same API were analysed to determine whether it was suitable for direct compression.

Prognostic value of chronic obstructive pulmonary disease in coronary artery bypass grafting.

Objective: Coronary and chronic lung diseases have become a common association. This comorbidity has been generically considered by most of the operative risk scores, but its functional severity has seldom been addressed by these models. Our objective was to analyze its prognostic relevance considering preoperative pulmonary function parameters.

Patient-prosthesis mismatch in aortic valve replacement: really tolerable?

Objective: Several studies have demonstrated favorable results despite patient-prosthesis mismatch after aortic valve replacement with the use of third generation prostheses. Our aim was to determine whether this mismatch is always tolerable.

Methods: A clinical-echocardiographic study has been performed in 339 consecutive patients who underwent aortic valve replacement because of aortic stenosis.

Left ventricular mass index in aortic valve surgery: a new index for early valve replacement?

Objective: Increased left ventricular mass index has been associated with higher mortality. We analyze the effect of increased left ventricular mass index on outcomes in patients undergoing aortic valve replacement.

Methods: Echocardiographic left ventricular dimensions were used to calculate left ventricular mass index in 614 patients who underwent aortic valve replacement between June 1993 and November 2001.

An unusual vascular graft infection by Aspergillus--a case report and literature review.

Vascular graft infection due to Aspergillus is a rare event. Only 11 previous case reports have been documented. All of these infections were in the aortic position, and infrainguinal arterial prosthetic graft involvement has been uncommon.

[Allergen analysis of mugwort pollen (Artemisia vulgaris) using crossed radioimmunoelectrophoresis and radioallergosorbent test inhibition].

It could be identified 43 antigens of mugwort pollen (Artemisia vulgaris), 31 migrating anodically and 12 cathodically, by means of crossed immunoelectrophoresis (CIE). Eleven antigens bound human IgE-antibodies in crossed radioimmunoelectrophoresis (CRIE). Two major allergens could be found, allergens 23 and 40.
