Ecthyma Gangrenosum Caused by Klebsiella Pneumoniae: A Rare Entity with Devastating Consequences.

This report describes the case of a 64-year-old female patient, with multiple comorbidities which presented an ecthyma gangrenosum due to Klebsiella pneumoniae confirmed by blood and tissue cultures. It finally ended in the amputation of the limb. The case is presented given the low prevalence of positive cultures for this microorganism in this pathology associated to devastating consequences for the patient.

[Isolation of Neisseria meningitidis in anorectal specimen in a men who have sex with men with uretritis and primary syphilis].

Neisseria meningitidis is a Gram-negative bacterium frequently associated with invasive diseases with high mortality. Although its natural reservoir is the human nasopharynx, in recent years there have been increasing reports of isolation of this agent in the anorectal mucosa, mainly in men who have sex with men (MSM). We present the case of an HIV-positive MSM who consulted for urethritis and primary syphilis, in which N.

Interplay of geomorphology and hydrology drives macroinvertebrate assemblage responses to hydropeaking.

Hydropeaking leads to major anthropogenic disturbance of river networks worldwide. Flow variations imposed by hydropeaking may significantly affect macroinvertebrate assemblages within the river network. As such, the responses of macroinvertebrate assemblages to hydropeaking are expected to be complex and vary across spatial and temporal scales as well as ecological organization levels.

Advantages and challenges of the implementation of a low-cost particulate matter monitoring system as a decision-making tool.

The integration of monitoring technologies in the last decades has been a key factor in the development of new ways to track air pollutants and supplementing the network of traditional monitoring systems. In this regard, the appearance of affordable and accurate sensor devices to monitor air quality has made possible to obtain relevant data about the state of the air, and moreover, eminent institutions are interested in promoting the use of novel and more affordable tools for air pollution, such as the United States Environmental Protection Agency and European institutions, within a new approach to environmental surveillance, known as Next Generation Compliance and Enforcement technologies. On other hand, in order to get more reliable measurements, the use of machine learning to support adjustment or calibration process has been used in some studies to improve the performance of monitoring devices.

[Assessment of moral competence of physicians].

Background: Moral competence (MC) in physicians is fundamental, given the increasing complexity of medicine. The "Moral Competence Test" (MCT © Lind) evaluates this feature and its indicator is the C Index (CI).

Aim: To explore moral competence and its associated factors among physicians working in Chile.
